Original potential control flotation technology for copper ore with unmanageable high-magnetic pyrite content

Abstract

The invention relates to an original potential control flotation technology for copper ore with unmanageable high-magnetic pyrite content. The technology regulates reasonable matching of flotation pulp potential and impact parameters such as a pulp pH value, medicament kind and amount, flotation time and the like, and controls flotation pulp potential within a proper range, thus effectively improving copper recovery by 3-5% compared with the traditional oredressing, realizing high-effectively selective flotation of copper minerals in copper ore with high-magnetism pyrite content and achievingthe purposes of improving sorting index, lowering production cost and simplifying flow structure. The technology has strong maneuverability, simple equipment, small pollution and high recovery rate, thus being suitable for low-grade copper sulphide ore resource with unmanageable pyrite content which is hard to process in the traditional oredressing technology, expanding resource utilization rangeand improving the comprehensive utilization ratio of copper resource.

Description

technical field [0001] The invention relates to a primary potential control flotation process for refractory copper ore with high pyrrhotite content, in particular to a copper sulfide ore with a high content of pyrrhotite and a fine particle size embedded in it. And flotation process pulp oxidation-reduction potential, reasonable matching with pulp pH value and reagent system and other parameters, to achieve efficient separation of pyrrhotite and copper sulfide ore, while simplifying the process structure and improving the separation index process. Background technique [0002] my country's sulfide ore and non-ferrous metal resources processing industry mainly adopts traditional flotation technology. Under the current technical conditions, traditional flotation technology has disadvantages such as high production cost, serious environmental pollution, and low comprehensive recovery of associated beneficial elements. It is difficult to process in the western plateau area. Non-...

Problems solved by technology

[0002] my country's sulfide ore and non-ferrous metal resources processing industry mainly adopts traditional flotation technology. Under the current technical conditions, traditional flotation technology has disadvantages such as high production cost, serious environmental pollution, and low comprehensive recovery of associated beneficial elements. It is difficult to process in the western plateau area. Non-ferrous metal mineral resources are difficult to efficiently recycle

For example, the high-sulfur copper ore in Saishitang, Qinghai is located in a plateau area, with low temperature and anoxic conditions, and harsh natural conditions. Due to the high content of pyrrhotite in the ore and the fine particle size of copper minerals, it is difficult to separate copper from sulfur and recover copper. A series of problems such as low efficiency, the traditional flotation process is difficult to achieve reasonable development and utilization
