Chapter 7. Depression of sphalerite with cyanide and zinc. activate the sphalerite in the zinc flotation circuit. Since chalcopyrite (0.3%) is also present in the Rosh Pinah Mine ore, it is believed that the dissolution and/or oxidation of chalcopyrite and galena can contribute to the presence of copper and ...

Pyrite floats at very low pH or gets entrapped during flotation. Column flotation will give good results for such problems. It has forth washing system where entrapped minerals are separated, to get very clean concentrate. 4 years of R&D in RDM proved to reduce silica from 7 to 3% in Zinc cleaning in column with very low pyrite.Reverse flotation of pyrite from a zinc-concentrate using. 01/10/1995· CONCLUSIONS Substituting nitrogen for air in reverse flotation of a Zn-concentrate selectively increased pyrite recovery: at 3% zinc recovery (i.e.loss) to the float product, nitrogen flotation increased pyrite recovery by about 5-10% (absolute) compared to air flotation.

some recent studies of copper ore flotation to separate chalcopyrite from pyrite with the evaluation of the effect of different important parameters on the process efficiency. Researchers have investigated (Martin et al., 1989, Leppinen, 1990, Boulton et al., 2001, Peng et al.,As an example of the beneficial effect of copper sulfate in the activation of zinc sphalerite toward flotation, the series of results shown in Fig. 1 is of interest.These represent rougher tests on a sample of heavy pyritic ore. The particular sample in question contained about 5.6% zinc as marmatite; and was treated in a circuit made alkaline with lime, using pine oil as a frother and ...

pyrite in zinc ore flotation mar. PDF 17 - Flotation of Gold Ores. In flotation of gold-containing base metal ores, a number of modifiers normally used for selective flotation of copper lead, lead zinc and copper lead zinc have a negative effect on the floatability of gold. Such modifiers include ZnSO. 4 ·7H.Pyrite In Zinc Ore Flotation In Iran. chalcocite pyrite ore flotation pyrite in zinc ore flotation in iran A low grade PbZn ore sample containing 31 pyrite and 44 dolomite and assayed at 234 Pb 691 Zn and 1536 Fe was prepared from the Kooshk mine in Yazd province Iran and used as the primary ore in flotation

The ore is characterized by a high lead-zinc oxidation rate (10-30%) and a large amount of easy-floating pyrite (20-30%). The zinc is mainly in sphalerite. The original production process is "concentration of lead, bulk flotation of zinc and sulfur".

pyrite in zinc ore flotation mar. New collectors for sphalerite flotation - ScienceDirect. 2006/06/01 · Flotation tests were done on a Canadian ore that contained about 2–3% copper, 7–8% zinc and about 15–20% iron. Chalcopyrite, sphalerite and pyrite were the main sulfidic mineral constituents of the ore. 2.2.1. Procedure for flotation testsration of copper and zinc minerals from pyrite [2]. However, with selective reagents in copper flotation, amount of sphaler-ite and fine-ground pyrite grows in the zinc flotation cycle, which mutilates flotation process. It is known that zinc cycle of copper–zinc ore flotation uses xanthate modifications that are not selective relative to pyrite.

Flotation of sphalerite and pyrite in the presence of. Pyrite is one of the major diluents of copper lead and zinc concentrates One explanation for the high flotation of pyrite in alkaline pH conditions is its inadvertent activation by copper either dissolved from copper minerals present in the ore or added in the zinc circuit to activate the flotation of sphalerite Bushell and Krauss 1962Pyrite In Zinc Ore Flotation In Iran.
