AI Technical Summary
In existing copper oxide ore flotation processes, the surface of copper oxide minerals is highly hydrophilic, making it difficult for conventional collectors to effectively adsorb them. The mineral composition is complex and the particle size is fine, resulting in low recovery rate and high reagent consumption. Existing combined systems lack synergistic effects, making it difficult to improve concentrate grade and recovery rate, and the applicable conditions are harsh.
A composite activator of N,N'-diphenylguanidine and ethylenediamine phosphate is used to synergistically activate the surface of copper oxide minerals, forming a stable hydrophobic adsorption layer and micro-dissolution activation, thereby improving the surface reactivity of the minerals. Combined with full-size deep sulfidation and selective inhibition, efficient flotation is achieved.
It significantly improves the recovery rate and concentrate grade of copper oxide ore, reduces reagent consumption, simplifies the process flow, reduces equipment modification costs, meets the requirements of green mining development, and improves resource utilization efficiency.
