【発明の詳細な説明】 浮選装置 本発明は、選鉱すべき鉱石及びその鉱石に添加される物質、即ち泡物質を処理す るセルと、泡物質をセルに供給するためにセルに導かれている供給パイプと、濃 縮物を集めるためにセルの頂部に配置されたフロスシュートと、選鉱滓をセルが ら運び出すために下部に配置された放出ダクトとを有する浮遊装置に関する。[Detailed description of the invention] flotation device The present invention deals with the treatment of ores to be beneficent and the substances added to the ores, i.e. foam substances. a supply pipe leading to the cell for supplying foam material to the cell; A floss chute is placed at the top of the cell to collect the shrinkage and the cell collects the beneficiation slag. and a discharge duct arranged at the bottom for transporting the floating device.
最近の浮選装置のセルでは、空気がばっ気装置によってセルの下部に導入されて いる。しばしば、泡物質を同時に攪拌する特殊なロータまたはその均等物がばっ 気装置として使用される。泡物質は攪拌装置のレベル(高さ)からセルに導入さ れる。この機構は懸濁状態でできるだけセル内の混合物を均質にする目的を持っ ている。泡物質内の濃縮物は空気泡に付着して空気と共に上昇する。濃縮物はセ ルの頂部に設けられた濃縮室に集められる。選鉱滓は下方に下がり、放出ダクト またはその均等物を通してセルから除去される。鉱石をこのような機構で選鉱す るとき、比較的多い量の濃縮物が選鉱滓に残る。さらに、装置は多量のエネルギ ーを要し、構成及び操作費用が高価である。In modern flotation cells, air is introduced into the bottom of the cell by an aerator. There is. Often special rotors or their equivalents are used to agitate the foam material at the same time. Used as an air device. Foam material is introduced into the cell from the level (height) of the stirring device. It will be done. This mechanism has the purpose of making the mixture in the cell as homogeneous as possible in a suspended state. ing. Concentrates within the foam material adhere to the air bubbles and rise with the air. The concentrate is It is collected in a concentration chamber located at the top of the bottle. The beneficiation slag is lowered down into the discharge duct or its equivalent removed from the cell. Ore is sorted using this kind of mechanism. When processing, a relatively large amount of concentrate remains in the tailings. Additionally, the equipment consumes a large amount of energy. It is expensive to configure and operate.
米国特許第2,922,521号は、泡物質がセルの底部のパイプを通してセル に吐出され、「きのこ」状の流れの移動がそれによって室内に発生されるような 、鉱物と他の物質を選別する装置を教示している。浮選に必要な空気が遠心ポン プの吸引側で泡物質に加えられる。空気は、選鉱すべき混合物を浮選室に入れる 前に、予め泡物質と混合させられる。攪拌手順は大部分機械的であり、多量のエ ネルギーを必要とし、機械的構造を摩耗させる。U.S. Patent No. 2,922,521 discloses that the foam material is passed through a pipe at the bottom of the cell. such that a “mushroom”-like movement of flow is generated within the room. , teaches an apparatus for separating minerals and other materials. The air necessary for flotation is pumped through a centrifugal pump. is added to the foam material on the suction side of the pump. Air enters the flotation chamber to feed the mixture to be beneficent beforehand, it is premixed with foam material. The agitation procedure is largely mechanical and involves large amounts of requires energy and wears out mechanical structures.
もし懸濁状態の混合物が短い距離でさえ例えばパイプ系を通して運ばれるならば 、泡の寸法が成長し易く浮選結果が実質的に改良されることが実際に見い出され た。泡の寸法をできるだけ小さく維持することはパイプ系内でエネルギーを消費 する乱流を必要とする。米国特許第4,639.313号は水溶性スラリーから 鉱物を選鉱する浮選装置を説明している。この公知の装置は、有利な空気/水混 合物を発生するための別個の、極めて複雑な装置を有している。有利な泡寸法を 混合物に維持する際、米国特許第2゜922.521号に開示された装置に伴う 同一の技術的な問題が生じる。If the suspended mixture is transported over even short distances, e.g. through a pipe system, It has actually been found that the bubble dimensions are easier to grow and the flotation results are substantially improved. Ta. Keeping the bubble dimensions as small as possible consumes energy within the pipe system requires turbulent flow. U.S. Patent No. 4,639.313 from an aqueous slurry It describes a flotation device for beneficiation of minerals. This known device has an advantageous air/water mixture. It has separate and highly complex equipment for generating the compound. Advantageous bubble dimensions In maintaining the mixture, the apparatus disclosed in U.S. Pat. No. 2,922,521 The same technical problem arises.

その主な理由は、セルの底部に沈殿した選鉱性が極めて小さいエネルギー消費で (別個の大きな、高価なポンプユニットなしで)浮選装置に再導入され、それに よって、浮選の成功に決定的な懸濁状態に乱暴なボン1作用から生じる乱流によ って乱れを生じさせることを避けることができるからである。The main reason is that the beneficiation deposited at the bottom of the cell has extremely low energy consumption. is reintroduced into the flotation equipment (without a separate large, expensive pumping unit) and Therefore, the turbulent flow resulting from the violent Bon 1 action affects the suspension state, which is critical to the success of flotation. This is because it is possible to avoid causing disturbances.

本発明の装置では、浮選化学物質を調整装置から供給される水に加えてもよく、 この場合、イに学物質は早期に加える必要はない。In the device of the invention, flotation chemicals may be added to the water supplied from the conditioning device; In this case, there is no need to add the chemical substance early.
以下の記載は新規な・浮選装置の使用の際得られる試験結果の評、 価である 。The following is an evaluation of the test results obtained when using the new flotation device. .
試験浮選が1、ケミラ オイのシーリンジャビのりん灰石鉱山で半年間本発明の プロトタイプの装置を用いて行われた。その結果が前記鉱山で用いられている機 械的な浮選装置と比較され、以下の内容が比較から見い出された。The test flotation was 1, and the invention was carried out for half a year at the apatite mine in Shirinjabi, Kemira Oy. This was done using a prototype device. The results are the machines used in the mine. It was compared with a mechanical flotation device, and the following findings were found from the comparison.
一層さい寸法の装置にかかわらず、泡物質の流入量を機械的セルと同一レベルに 維持できた。Same level of foam material inflow as mechanical cells, despite the smaller size of the device I was able to maintain it.
−ヘッドを用いると、第1試験で得られた生産量は機械的セルと同レベルであり 、成る粒度の範囲では明らかに良好でさえあり、いわゆる反転浮選による雲母の 分離用の予備試験では、驚くべき良好な結果が得られた。かくして、この試験結 果により−ケミラオイは雲母分離能力の一層厳密な正確さを得る拡張的な試験浮 選を研究部門に命令することになった。- With the head, the production yield obtained in the first test was on the same level as with the mechanical cell. , even clearly good in the particle size range consisting of mica by so-called inverse flotation. Preliminary tests for separation showed surprisingly good results. Thus, this test result As a result, Chemilaoi is now able to conduct extensive testing to obtain even more precise mica separation capabilities. The decision was made to order the research department to make the selection.
−装置の効率性と装置に要する投資費用の有効性が得られる実験から、鉱物の選 鉱での全体的な利点の観点により開発された新規な形式の空気浮選装置が最も重 要であるということが推測される。− The selection of minerals is based on experiments that show the efficiency of the equipment and the effectiveness of the investment cost of the equipment. A new type of air flotation device developed with a view to its overall benefits in mining is the most important It is assumed that this is important.
比較試験に関して、それぞれ予備浮選及び反復浮選から得られた結果に関連する 第6図及び第7図を参照する0曲線17及び15は、それぞれ、新規な空気セル の使用の際に得られたものであり、曲線16及び14は、それぞれ、従来の機械 的セルの使用の際得られたものである。試験は同一の泡物質を両方のセルに交互 に同時に供給することによって行われた。測定(濃縮物、泡物質、脈石及びP2 O5のパーセント)がサンプルに対して同時に行われた。Regarding comparative tests, relating to the results obtained from pre-flotation and repeated flotation, respectively. 0 curves 17 and 15 with reference to FIGS. 6 and 7 respectively represent new air cells. curves 16 and 14, respectively, were obtained when using a conventional machine. This was obtained when using a target cell. The test alternates the same foam material into both cells. This was done by simultaneously supplying Measurements (concentrates, foam materials, gangue and P2 05%) was performed on the samples at the same time.
予備浮選比較試験の結果は、新規な空気セルを使用すると、公知の機械的なセル を使用するよりも実質的に良好d生産量(約10%)が得られることを示してお り、脈石に残るりん灰石(P2O5)の量を実際に減少させている。The results of preliminary flotation comparison tests show that the use of the new air cell and the known mechanical cell It has been shown that substantially better yields (approximately 10%) can be obtained than using actually reduces the amount of apatite (P2O5) remaining in the gangue.
新規な空気セルを使用する反復浮選比較試験で得られた濃縮物のパーセントはさ らに極めて高く、即ち、公知のセルの使用の場合と少なくとも同一レベルである が、生産量は、平均で、10%以上高い。The percentage of concentrate obtained in a repeated flotation comparison test using the novel air cell was Furthermore, it is very high, i.e. at least on the same level as in the case of using known cells. However, production is, on average, more than 10% higher.
新規な装置を鉱物の選鉱に主に関連して説明してきたが、酸化を望む泡物質また はその構成粒子を選別したい泡物質と共にも使用できることは明らかである。Although the novel device has been described primarily in connection with mineral beneficiation, it may also be used to It is clear that it can also be used with foam materials whose constituent particles are desired to be sorted.
