Research and Application of Copper Oxide Flotation Frothing Agent

And collector, activators and inhibitors comparison, study and practice of copper oxide ore flotation frother is relatively less, but made some progress. The application of new foaming agents such as phenethyl ester oil, P-8201 and TF-95 in different factories and mines has also proved to be an effective foaming agent for copper minerals.

Kunming Institute of Metallurgy successfully developed novel blowing agent phenethyl oil (abbreviated B633), selected from the plant through the Muding copper from small industrial test trials practice, three phases of the trial production, proved to be a completely Instead of high-efficiency foaming agent for pine oil, the amount of phenylethyl ester is only 60% to 65% of pine alcohol. The selection index and economic effect are similar to those of pine oil. If phenylethyl ester can be mass produced in batches and the price is lowered, it will show its economic superiority.

Kunming Metallurgical Research successfully developed another new foaming agent P-8201 (its molecular formula C10H10), the small test and industrial practice of the Luding copper mine proved that the use of P-8201 comparable to pine oil saved 8,000 yuan, proving it to reduce The cost of mineral processing has a certain effect on improving the economic benefits of the mine.

The industrial foam test results of a combined foaming agent TF-59 developed by the Dongchuan Mining Bureau Research Institute showed that TF-59 and P-8201 were mixed with P-8201 alone, and the recovery rate was unchanged. Next, the concentrate grade increased by 2%.
