Thus, when a copper sulfide ore having a minor amount of molybdenite is subjected to flotation, a much larger amount of reagent is required. If the ore is a primary molybdenite ore or molybdenite concentrate containing small amounts of copper sulfide, lesser amounts of reagents are required to depress the copper and other metal sulfides.

Jan 22, 2020 A common problem recently encountered with the increase in the rate of input feed at Enrichment Plant 2 of the Sarcheshmeh Copper Complex is the loss of value to the tails, translating to lower recoveries. The feasibility of the direct transfer of part of the high-grade concentrate from rougher stages to an appropriate position along the circuit was studied, and two positions were proposed for ...

The primary sulphide concentrate from the rougherscavengers is cleaned using conventional mechanical flotation cells. The cleaned molybdenum and copper concentrate is pumped to the separation flotation circuit, conditioned with reagents to depress copper and produce a rougher molybdenum concentrate and a copper tailing.

Jul 01, 2007 The influence of reagents, commonly used to hydrophobise sphalerite, was also studied. To accomplish this, a combination of flotation tests, rheology and zeta potential measurements were applied. At pH 9 and in the absence of reagents, clean silica particles report to the sphalerite concentrate essentially via the entrainment mechanism.

Copper concentrates are mainly produced by flotation. The ore is crushed and milled to a particle size of less than 100 m. This produces a mix of particles containing pure phases of primary or secondary copper sulfides. The ground ore is mixed with water and reagents, to form a slurry, where the copper sulfide mineral particles
