Problems solved by technology

Production practice shows that the recovery rate of fine-grained copper sulfide minerals is decreasing year by year by the traditional pharmaceutical system, which also leads to a decrease in the recovery rate of cobalt minerals closely associated with copper sulfide minerals.
In particular, the existing flotation reagent system has a weaker ability to collect cobalt minerals that exist in the form of independent minerals (not closely associated with copper sulfide minerals) in the ore
The above two situations lead to a large amount of cobalt minerals being discharged into the tailings pool along with the tailings, resulting in a large waste of rare and precious metal resources

Abstract

The invention provides a flotation agent combination for improving the recovery rate of associated cobalt in fine-grained copper sulfide ore, which comprises O-butyl-N-hydroxyethyl-thiocarbamate 90-95% by weight 1-5 parts of biphenylglyoxaloxime, 1-5 parts of α-nitroso-β-naphthol, and 1-5 parts of di(2,4,4-trimethylpentyl)phosphonic acid. The combination of flotation agents provided by the present invention not only takes into account the recovery of cobalt minerals closely associated with fine-grained copper sulfide minerals but also the recovery of independent cobalt minerals in the ore. Compared with traditional collectors, the composition can improve The recovery rate of cobalt is more than 3 percentage points.

Description

technical field [0001] The invention relates to the technical field of mineral processing, in particular to a flotation agent combination for improving the recovery rate of associated cobalt in fine-grained copper sulfide ore. Background technique [0002] There are very few independent cobalt deposits in nature, and the cobalt minerals in copper sulfide deposits are an important source of cobalt metal. However, due to the low grade of cobalt in the ore, the recovery of cobalt has been carried out along with the recovery of the main metal in the ore deposit. Most concentrators have not set up a separate chemical system or process for the recovery of cobalt minerals. In recent years, with the increase of the amount of cobalt metal, the price of cobalt metal in the ore has even exceeded the price of copper metal, and the recovery of cobalt in copper sulfide ore has gradually attracted great attention. However, most domestic concentrators' processes and reagent systems are des...
