Embodiment 1

[0018] A combined collector for copper oxide ore flotation, which is made by mixing three kinds of reagents: benzohydroxamic acid, xanthate and fatty alcohol polyoxyethylene ether in a weight ratio of 75:22:3.

[0019] A method of beneficiation of copper oxide ore using the above-mentioned combined collector, the present embodiment adopts Congo (golden) copper oxide ore to carry out, wherein the main chemical composition analysis results of the ore are shown in Table 1, and the copper phase analysis is shown in Table 2 , the specific operation steps are as follows:

[0020] Step 1: grind the ore to a particle size of -200 mesh and a content of 77%, add 800 g / t of sodium carbonate and 1,200 g / t of sodium sulfide as regulators for the first roughing, and then add the above-mentioned combined collector at a dosage of 166 g / t t, then add 2# oil 36g / t as a foaming agent, and then carry out the second roughing, the amount of combined collector in the second roughing is halved compar...

Abstract

The invention belongs to the technical field of beneficiation collectors, in particular to a combined collector in flotation of copper oxide ores and a using method thereof. The combined collector isformed by mixing benzohydroxamic acid, proxan sodium and fatty alcohol-polyoxyethylene ether according to the weight ratio of 75:22:3. The combined collector in flotation of the copper oxide ores andthe using method thereof have the advantages that the problem that the grade and the recovery rate of copper oxide concentrates are low in a conventional method can be solved, higher efficiency for collecting malachite-oriented and chrysocolla-oriented copper oxide minerals by using the combined collector can be achieved, the combined collector can be reduced, the technological process is simple,meanwhile, better qualified products of the copper oxide concentrates can be obtained, and the economic benefits of enterprises can be improved.

Description

technical field [0001] The invention belongs to the technical field of ore dressing collectors, in particular to a combined collector for flotation of copper oxide ore and a usage method. Background technique [0002] Copper oxide ore is an important part of the world's copper resources, and its reserves are relatively abundant. Most of the sulfide deposits have oxide ore belts in the upper part, and some deposits have even been oxidized into large and medium-sized oxide deposits. Most of the copper oxide deposits have mud High degree of flotation, poor floatability, complex ore properties, low flotation recovery rate and other problems. In recent years, due to the reduction of ore mining grades, the development and utilization of refractory copper oxide ores has attracted more and more attention. In addition to the vulcanization-xanthate method, chelation flotation, chemical beneficiation, and microwave irradiation flotation have also appeared. , hydrothermal sulfidation f...
