종래의 기술은 고품위 장석 원광석을 파쇄-분쇄하여 각종 요업용으로 사용하였으나, 그 양이 거의 소진되어 사용이 어렵게 되었으며, 일부 저품위 장석을 파쇄-분쇄-마광-분급한 후, 각종 시약류를 광액에 첨가하여 각종 불순광물을 부유제거한 후 장석정광을 회수하는 부유선별방법을 적용하였으나, 각종 시약에 의한 공해문제 및 생산성 한계, 생산비상승등이 문제시되어 왔다. 또한 일부 저품위 장석은 채광-사분-자력선별에 의하여 장석정광을 회수하였으나, 품질의 균일성을 유지하기가 어려운 형편이었다.The prior art crushed-crushed high-grade feldspar ore was used for various ceramics, but its amount was almost exhausted, making it difficult to use, and after adding some low-grade feldspar, crushed-grinded-classified, various reagents were added to the mineral liquid. As a result, a flotation screening method for recovering feldspar concentrate after removing various impurities has been applied, but pollution problems, productivity limitations, and production rise due to various reagents have been considered. In addition, some low-grade feldspar recovered feldspar concentrate by mining-quadrant-magnetic screening, but it was difficult to maintain uniformity of quality.
본 발명은 상기와 같은 문제점을 해결하기 위하여 저품위 장석광으로부터 고품위 장석정광을 선택적으로 분리회수하기 위하여 원광석을 파쇄-분쇄-마광-습식분급 한 후, 나선형 고속 비중분리와 습식 고자력 선별을 함으로서 고품위 장석정광만을 경제적으로 분리할 수 있도록 하였으며, 분리회수된 고품위 장석정광을 진동탈수기로 탈수하여 용도에 따라 직접 사용하기도 하고, 일부는 건조하여 사용하기도 하는 방법을 적용한 것에 그 목적이 있다.In order to solve the above problems, in order to selectively recover the high-quality feldspar concentrate from the low-grade feldspar ore, the ore is crushed-crushed-grind-wet-classified, followed by spiral high-speed specific gravity separation and wet high magnetic screening. Economical separation of feldspar concentrate is economical. The purpose is to apply the method of dehydrating the recovered high-quality feldspar concentrate using a vibrating dehydrator, which is used directly according to the purpose, and partly dried.
상기와 같은 목적을 달성하기 위하여 본 발명은 저품위 장석 원광석을 1, 2차 파쇄한(3, 5)후, 이를 다시 분쇄(7) 또는 마광하여 광석입도를 0.5㎜ 크기 정도로 하여 물과 함께 적정 광액농도 조건에서 나선형 고속비중분리기(11) 상부에 급광하면, 분리기의 홈통을 따라 광액이 고속류강하면서 하부에 다달을 때 고비중의 불순광물들을 분리제거하고, 나머지 장석정광을 회수하고 이를 펌푸(15)를 사용하여 습식 회전형 고자력선별기(13)에 급광하면 자력특성을 갖는 불순광물들을 흡인 제거하고 나머지 장석정광을 유출시키면 이를 펌푸(15)로 진동탈수기에 급광하여 탈수하고, 건조기(19)로 건조시켜 포장기(21)로 포장하여 출하할 수 있는 것을 특징으로 한다.In order to achieve the above object, the present invention first and second crushed low-grade feldspar ore (3, 5), and then again crushed (7) or polished to a mineral ore with a degree of 0.5mm ore suitable mineral water with water When the concentration is rapidly flashed on the upper part of the spiral high-speed specific gravity separator 11, when the mineral liquid reaches the lower part with high velocity flow along the separator's trough, high-density impurities are separated and removed, and the remaining feldspar concentrate is recovered and pumped (15). When the wet rotary type high magnetic separator (13) is used to sharply remove the impurities having magnetic properties by suction, and the remaining feldspar concentrate flows out, the pump is discharged by sharpening the vibration dehydrator with a pump (15) and the dryer (19). It is characterized in that it can be shipped by packing with a packaging machine 21 by drying.
이하 발명의 요지를 그 공정 및 실시예에 연계하여 상세히 설명하면 다음과 같다.Hereinafter, the gist of the present invention will be described in detail with reference to the process and the examples.
본 발명의 정제방법을 제1도에 표시된 공정 및 기계장치에 따라서 다음과 같이 설명한다. 저품위 장석 원광석의 최대크기 500∼600㎜ 정도되는 것들을 흡바(1)에 적재하고, 이를 급광기(2)를 통하여 계획된 처리량에 따라 시간당 일정량씩 1차 파쇄기(3)에 급광하여 장석의 최대크기를 100㎜정도로 1차 파쇄한 후, 파쇄된 산물을 벨트콘베아(4)에 의해 2차 파쇄기(5)로 급광하여 광석의 크기 10㎜ 이하로 2차 파쇄하여, 홉바(6)에 적재한다. 2차 파쇄된 산물은 분쇄기(7)로 보내져 약 3㎜ 크기로 분쇄 시킨 후 사분하여, 사상산물은 다시 분쇄기(7)로 급광하고, 사하산물은 원통형 습식사분기(9)에 물과 함께 급광하여 0.5㎜ 크기 이상되는 사상산물은 일반 요업용으로 사용토록하고, 사하산물은 펌푸(10)를 통하여 나선형 고속 비중 분리기(11)에 급광시킨다. 0.5㎜ 크기 이하의 분쇄된 산물과 물이 혼합된 광액이 나선형 고속 비중 분리기에 급광되면, 비중이 높은 불순광물들이 나선형 홈통의 안쪽을 따라서 그리고 비중이 낮은 장석등은 홈통의 바깥쪽을 따라 고속으로 류강하면서 분리되어 1차 장석정광을 회수하고, 이를 펌푸(12)로 다시 습식 회전형 고자력 선별기(13)로 급광하면 자성특성을 갖는 각종 불순광물들이 제거되고 고품위 장석정광이 회수 된다. 이러한 고품위 장석 최종정광은 수요자의 요구에 따라 펌푸(15)로 진공탈수기(16)에 급광하면, 탈수된 고품위 장석정광이 벨트콘베아(17)로 적재장에 적재되어 직접 출하하거나, 운반기기(18)를 사용하여 건조기(19)에 다시 급광하여 건조시킨후 이를 감응롤형 건시고자력 선별기(20)에 급광하여 나머지 철성분 광물들을 완전제거 한 후 건조된 정제장석을 벨트콘베아(21)를 통하여 포장기(22)로 적정량씩 포장하여 각종 도자기 및 유리업계 수요자들에게 출하할 수 있다.The purification method of the present invention will be described as follows according to the process and mechanism shown in FIG. The maximum size of low-grade feldspar ore is loaded into the suction bar (1), and then it is suddenly lightened to the primary crusher (3) by a certain amount per hour according to the planned throughput through the flasher (2) to maximize the size of the feldspar. After primary crushing to about 100 mm, the crushed product is sharpened by the belt crusher 4 to the secondary crusher 5, and secondary crushed to 10 mm or less in size of ore, and loaded on the hop bar 6. The secondary crushed product is sent to the grinder (7), pulverized to about 3 mm in size, and then divided into four, the filamentous product is sharply returned to the grinder (7), and the dead product is dripped with water in the cylindrical wet mill (9). The filamentous product having a size of 0.5 mm or more is to be used for general ceramics, and the bottom dead product is sharpened to the spiral high speed specific gravity separator 11 through the pump 10. When the pulverized product of 0.5 mm or less mixed with water is sharpened in the spiral high-speed specific gravity separator, high-density impurity minerals flow along the inside of the spiral gutter and low-density feldspar, etc., along the outside of the gutter. The primary feldspar concentrate is recovered while being separated by a strong steel, and then, by rapidly pumping the feldspar concentrate into the wet rotary type high magnetic separator 13, various impurities having magnetic properties are removed and high quality feldspar concentrate is recovered. Such high-quality feldspar final concentrate is rapidly pumped to the vacuum dehydrator 16 by the pump 15 according to the demand of the consumer, and the dehydrated high-quality feldspar concentrate is loaded into the loading station by the belt conveyor 17 or shipped directly, After drying by drier again in the dryer (19) using a) and then immersed in the sensitive roll type dry and magnetic separator (20) to completely remove the remaining iron minerals, the dried tablet feldspar through the belt conveyor (21) The packaging machine 22 may be packaged in appropriate amounts and shipped to various ceramic and glass industry users.
(실시예)(Example)
표-1의 품위를 갖는 저품위 장석 원광석을 1,2차 파쇄하고, 이를 다시 분쇄-사분하여 약 0.5㎜ 크기 이하되는 시료를 약 20∼25㎏ 정도 준비한다. 이 시료를 탱크에 넣고 물을 첨가하여 광액의 농도가 약5% 고체 정도되게 한 후, 이 광액을 샌드 펌푸로 나선형 고속 비중분리기 상부에 공급하며 광액은 나선형 비중분리기의 홈통을 따라 고속으로 류강하므로서 본 분리기 하부에서는 고 비중의 불순광물, 장석정광 및 스라임등의 3가지 산물로 각각 분리된다. 이때 1차 장석정광의 물량을 조절하면 광액 농도가 약 10% 고체정도로 되게한 후, 습식 고자력 선별기에 일정시간동안 공급하면 자성특성을 갖는 각종 불순광물들은 자력선별기에 의해 회수 제거되고, 나머지 장석정광만이 고자력선별기를 통과하여 흘러나오게 되며 이를 탈수하여, 다시금 건조시켜 최종 장석정광을 생산하게 된다.The low-grade feldspar ore having the grades of Table-1 was first and secondly crushed, and crushed and divided again to prepare a sample having a size of about 0.5 mm or less and about 20 to 25 kg. The sample is placed in a tank and water is added to make the concentration of the mineral liquid about 5% solids. Then, the mineral liquid is supplied to the upper portion of the spiral high speed specific gravity separator by sand pump, and the mineral liquid flows at high speed along the trough of the spiral specific gravity separator. In the lower part of this separator, it is separated into three products, high specific impurity mineral, feldspar concentrate and slime. At this time, if the amount of primary feldspar concentrate is adjusted, the concentration of the mineral solution is about 10% solids, and when supplied to the wet high magnetic separator for a predetermined time, various impurities having magnetic properties are recovered and removed by the magnetic separator, and the remaining feldspar crystal Only light flows out through the high magnetic separator, which is dehydrated and dried again to produce the final feldspar concentrate.
이때 최종 장석의 품위는 다음 표-2와 같다.The final feldspar is shown in Table 2 below.
이와같은 본 발명과 비교 검토하기 위하여 똑같은 저품위 장석원광석을 1,2차 파쇄하고, 이를 다시 분쇄 사분하여 약 0.5㎜ 크기이하되는 시료 1㎏을 준비하여 각종 시약류를 사용하는 부유선별 실험을 다음 제2도에 의거하여 실험하였다. 제2도에 나타난 바와같이 시료 1㎏을 부유선별기에 넣고, 물을 채워 광액의 농도를 30∼35% 고체농도되게하고, 1차로 운모와 같은 불순광물을 제거하기 위하여 광액의 수소이온농도를 3.5pH 되게 하기위하여 황산을 첨가하고 포수제인 Armac T를 약 100g/T, AP825를 약 100g/T을 첨가하고, 기포제 시약인 AF 65를 약 20g/T 정도를 첨가하여 운모를 회수하되 이와같은 작업을 1∼2회를 계속 반복하여야 하며, 부유선별기 쎌에 침하된 산물광액에 다시금 광액의 수소이온 농도를 3.0으로하고 AP 825를 약 100g/T, AP 845를 약50g/T, AF65 20g/T등 시약류들을 적정량 첨가한후, 부유선별하여 산화철 및 석류석등을 부유제거한다. 이때 부유선별기 쎌에 침하된 산물을 다시금 수소이온 농도를 6.0pH 정도로 맞추고, 유화물포수제(쟌세이트-6을 약 100g/T), 기포제(AF 65)를 약 20g/T 정도로 각각 적정량씩 사용하면 각종 유화 광물들을 부유제거하게 된다. 이때 부유선별기 쎌에 침하된 산물을 탈수-건조하여 최종장석정광을 회수하고, 산품의 품위는 다음 표-3과 같다.In order to compare and compare with the present invention, the same low-grade feldspar ore was first and secondly crushed, and then divided into four pieces, and then prepared into 1 kg of a sample having a size of about 0.5 mm or less, followed by a flotation experiment using various reagents. Experiment was based on the figure. As shown in FIG. 2, 1 kg of the sample is placed in a flotation sorter, filled with water to make the concentration of the mineral liquid 30 to 35% solids, and the hydrogen ion concentration of the mineral liquid is 3.5 to remove impurities such as mica. To make the pH, add sulfuric acid, add about 100g / T of Armac T, a catcher, about 100g / T of AP825, and add about 20g / T of foaming agent AF 65 to recover the mica. Repeat this one or two times. In the product mineral solution submerged in the flotation system, the hydrogen ion concentration of the mineral solution is 3.0 again, and AP 825 is about 100g / T, AP 845 is about 50g / T, AF65 20g / T, etc. After adding the appropriate amount of reagents, by flotation, iron oxide and garnet are removed. At this time, adjust the hydrogen ion concentration to 6.0pH again with the product settled in the flotation separator, and use the appropriate amount of emulsion catcher (Wixate-6 about 100g / T) and foaming agent (AF 65) about 20g / T. Various emulsion minerals are suspended. At this time, the product immersed in the flotation separator is dehydrated and dried to recover the final feldspar concentrate, and the product quality is shown in Table 3 below.
그러므로 본 발명에의한 정제방법은 다른방법의 정제장석을 회수하는 방법보다 생산성이 아주 높고 처리비용도 낮으며 시약류등을 사용하지 않으므로, 환경문제에 어려움이 없을뿐 아니라, 종전의 부유선별방법시 사용되던 시약류의 전량을 거의 수입에 의존하였지만, 금번 본 발명에서는 시약류를 사용치 않으므로, 외화절감효과를 거둘 수 있게 되었으며, 국내의 유리 또는 도자기업계에 안정적인 정제장석을 적당한 가격으로 무한정 공급할 수 있게 되었다.Therefore, the purification method according to the present invention is much higher in productivity than the other method for recovering feldspar, has a lower processing cost, and does not use reagents. Although the total amount of the reagents used was almost dependent on imports, since the reagents are not used in the present invention, foreign currency saving effect can be achieved, and stable refined feldspar can be supplied to domestic glass or ceramics industry at an affordable price indefinitely. .
