Abstract

The invention provides a copper suppression inhibitor, a preparation method and a copper-containing mineral flotation method. The copper inhibition inhibitor of the present invention is made from the following raw materials: urea, sodium carbonate, sodium hydroxide and potassium ferrocyanide. The preparation method of the copper inhibition inhibitor of the present invention is prepared by grinding the above-mentioned raw materials, quantitative mixing and roasting under a protective atmosphere. The copper-containing mineral flotation method of the present invention adopts the above-mentioned formula, and carries out the flotation of the copper-containing mineral through the sequence of mineral pulping, adding the copper inhibition inhibitor of the present invention, adding a collector and a foaming agent. The copper inhibition inhibitor, preparation method and copper-containing mineral flotation method of the present invention do not introduce harmful substances such as arsenic and phosphorus that are harmful to the environment during use, and have relatively high environmental friendliness while less polluting the concentrate At the same time, it also has the characteristics of small dosage, good selectivity, good inhibitory effect, and not easy to oxidize and fail.

Description

technical field [0001] The invention relates to the technical field of mineral processing, and relates to a mineral processing agent, a preparation and a mineral processing method, in particular to a copper suppression inhibitor, a preparation method and a copper-containing mineral flotation method. Background technique [0002] At present, my country's mineral resources are poor, fine, and hybrid phenomenon is becoming more and more serious. As important mineral resources for national production in my country, non-ferrous metals such as copper, molybdenum, and lead are mostly in the form of symbiotic and associated ores, and their grades are low. It is difficult to recycle these resources. In the flotation process research of copper, molybdenum, lead and other associated ores, the separation of copper-molybdenum mixed concentrate and copper-lead mixed concentrate is the most important and difficult point in the treatment of associated ores, and it is also an important factor...
