Description
Technical field
The beneficiation method that the present invention relates to a kind of high carbon acid calcium type fluorite ore, belongs to technique of preparing field.
Background technology
Fluorite is a kind of strategic mineral, and the fluorite deposit with industrial significance is distributed in all over the world.In fluorite, containing halogen fluorine, is unique raw material of producing hydrofluoric acid, is the primary raw material of producing fluorochemical.China is fluorite resource big country, but Fluorine in Ores calcium average content is only 34.7%, and high-grade rich ore only accounts for national total amount 2%.The feature of the flworite resources of China is: single type fluorite deposit (point) is many, but reserves are few, and the raw type mineral deposit of companion's (being total to) (point) number is few, but reserves are large; Lean ore is many, and rich ore is few; Difficult ore dressing is many, and easily ore dressing is few.In fluorite reserves, the comprehensive reutilization technical matters of most mines fluorite, still among research, does not also have practical application.The fluorite ore of occurring in nature mainly contains 3 types, i.e. quartz-fluorite type, quartz-fluorite-barite type, quartz-fluorite-calcium carbonate type, and its method for separating is decided by its final use.Due to floatability fairly similar and the difficult choosing of fluorite and calcium carbonate, therefore, such fluorite ore belongs to difficult ore dressing.Degree of its difficult choosing mainly determine according to the ratio of fluorite content and calcium carbonate content again, and the less fluorite ore of ratio more difficulty selects, and generally ratio is less than to 4～5 fluorite ore divides difficulty into and selects fluorite ore.
Flotation is to reclaim fluorite ore effective method the most, but because the flotation nature of calcium carbonate and fluorite is close, while using fatty acid as collecting agent in actual flotation operation, fluorite and calcium carbonate all have strong suction-operated, are difficult to well separated these two kinds of mineral.The inhibitor of the calcium carbonate of generally selecting in production has waterglass, sodium metaphosphate, lignosulfonates, dextrin, tannic acid, tannin extract etc., in order to improve inhibition, mainly with combination medicament form, adds flotation pulp.In floatation process, often there are two kinds of situations: (1) inhibitor adds when less, and calcium carbonate could not be suppressed preferably, makes the fluorite grade of concentrate not high, is difficult to reach the index request of high grade fluorite concentrate; (2) when calcium carbonate is suppressed preferably, inhibitor also can suppress part fluorite ore thing simultaneously, and this can cause the rate of recovery of fluorite in concentrate obviously to decline.Particularly, when calcium carbonate mineral content is higher, above two kinds of situations are more obvious.
In addition, adopt predictive desliming, the techniques such as stage grinding classification, exist the concentrate rate of recovery low equally, and the problem that product quality is not high, so the application of these technology is also few.
Summary of the invention
For problem and the deficiency of above-mentioned prior art existence, the invention provides a kind of beneficiation method of high carbon acid calcium type fluorite ore.The method is for a large amount of fluorite ore resources because of fluorite and the formation of calcium carbonate mineral separation difficulty, the beneficiation method of high efficiente callback fluorite ore resource from fluorite ore is provided, and utilize the method separating effect good, Fluorite recovery rate is higher, and the present invention is achieved through the following technical solutions.
A beneficiation method for high carbon acid calcium type fluorite ore, its concrete steps are as follows:
(1) floatation process: be first that 74 μ m account for 78% ~ 92% below by high carbon acid calcium type fluorite ore ore grinding to granularity, then successively add ore pulp adjusting agent sodium carbonate, gangue inhibitor acidified sodium silicate, collecting agent enuatrol flotation 6 ~ 8min, can obtain fluorite rough concentrate;
(2) six refining process: the fluorite rough concentrate that step (1) is obtained carry out six times selected, from for the third time selected to the 6th selected each process all order add gangue inhibitor acidified sodium silicate, tannic acid, through six times, obtain fluorite concentrate ore pulp after selected;
(3) acidleach process: add hydrofluoric acid to mix after the fluorite concentrate slurry concentrating that step (2) is obtained and leach 10 ~ 15min, can obtain high-grade fluorite concentrate after liquid-solid separation.
Described high carbon acid calcium type fluorite ore comprises following mass percent component: fluorite 31.49 ~ 39.27%, calcium carbonate 16.18 ~ 25.62%.
The consumption of described sodium carbonate is that high carbon acid calcium type fluorite ore per ton adds 1.5 ~ 2kg sodium carbonate.
Described acidified sodium silicate is that mol ratio is the acid of 1:1 and the mix reagent of waterglass, in the floatation process of step (1), acidified sodium silicate consumption is that high carbon acid calcium type fluorite ore per ton adds 1.5 ~ 2.5kg acidified sodium silicate, and in the refining process of step (2), the total consumption of acidified sodium silicate is that high carbon acid calcium type fluorite ore per ton adds 2 ~ 4kg acidified sodium silicate.
Described enuatrol consumption is that high carbon acid calcium type fluorite ore per ton adds 300 ~ 600g enuatrol.
The total consumption of described tannic acid is that high carbon acid calcium type fluorite ore per ton adds 90 ~ 180g tannic acid.
Described hydrofluoric acid consumption is that high carbon acid calcium type fluorite ore per ton adds 10 ~ 20kg hydrofluoric acid.
According to the high grade fluorite concentrate of described beneficiation method gained grade, be greater than 97.5%, the rate of recovery is greater than 82%, and concentrate impurities content is all lower than target level of product quality, and separating effect is good.
In above-mentioned steps (1), grinding process is wet-milling.
Involved in the present invention to chemical equation be:
