Problems solved by technology

[0003] The present invention provides a method for the application of kerosene in the separation of sulfide ores, which can effectively solve the problem that the buoyancy of useful minerals or useless minerals will change due to the influence of the medicament and other factors in the previous operation section mentioned in the background technology, increasing the The difficulty of separation will lead to a reduction in the purity of the ore after flotation, and before flotation, the ore raw materials need to be crushed, ground and stirred. After stirring, more ore pulp will stick to the inner wall of the mixer. If the ore pulp is not Processing and recycling is a waste of ore resources. After flotation, the tailings will contain a large amount of flotation agents. If the tailings are directly subjected to secondary flotation, the content of minerals after flotation and Purity is reduced, resulting in low flotation efficiency

Abstract

The invention discloses an application method of separating kerosene from sulphide ores. The application method comprises the steps of crushing, ball milling, a grading, stirring, floatation, scraping, flushing, separating and recycling. According to the application method, steps are reasonable, using is safe and convenient, and proper kerosene is added in the separating process of the sulphide ores to replace an inhibitor of certain ores, so that the flotation environment of the sulphide ores is effectively improved, the purity and effect of flotation of the sulphide ores are improved, the floatation degree of the sulphide ores is greatly improved, and the efficiency of flotataion of the sulphide ores is improved. Cleaning can be conducted after stirring, so that stirred ore pulp is effectively prevented from being adhered to the inner wall of a stirrer. On the one hand, the clean degree of the inner wall of the stirrer can be guaranteed; and on the other hand, waste of the ore pulp can be effectively avoided, and the floatation yield of the sulphide ores is improved.

Description

technical field [0001] The invention relates to the technical field of sulfide ore separation, in particular to a method for applying kerosene in the separation of sulfide ore. Background technique [0002] Ore refers to mineral aggregates from which useful components can be extracted or which have certain properties that can be used. In polymetallic beneficiation, it contains both sulfide ore and oxide ore. Due to continuous operation, generally all Sulfide ore is flotation first, and then oxidized ore is flotation. For sulfide ore mixed ore with two or more different useful metals, it is necessary to separate the different metals. Due to the influence of the reagents and other factors in the previous operation section , the flotability of useful minerals or useless minerals will change, increasing the difficulty of separation, which will lead to a decrease in the purity of the ore after flotation, and, before flotation, the ore raw materials need to be crushed, ground and ...
