Can you list the factors affects the floatability of pyrite from refractory low grade ore.I used a Wemco lab flotation cell and aimed on analysing factors like collector dosages (PAX), Activator (Copper sulphate),MIBC , pH and others like pulp density and particle size (70 and 150 microns) .However

Pyrite Activation in the Lead-Zinc Tailings Recovery - Xinhai

Most non-ferrous metals are metal sulfides ores, such as lead-zinc ore, copper sulfide, which often coexist with a large number of pyrites.Pyrite is the main raw material for industrial sulfuric acid, but China is a leading manufacturer and consumer of sulfuric acid, so the comprehensive utilization of pyrite plays an important role in lead-zinc tailings recovery.

Method of floatation of copper-zinc-pyrite ore (versions)

The closest in technical essence is the way the bulk flotation of copper-zinc-pyrite ore in two steps, including grinding in a calcareous environment, air conditioning with collector - butyl of xanthene the ohms and a foaming agent, collective flotation of copper minerals and natural activated sphalerite, and then with the addition of copper sulphate platinuum sphalerite with weak natural activity; zinc concentrate flotation can be directed straight to the main zinc flotation cycle ...

Oct 15, 2020 · Pyrite Flotation. The purpose of the pyrite flotation circuit will be to recover pyrite prior to the barite flotation circuit. The zinc flotation tailings report to a conditioning tank, where sulphuric acid, copper sulphate, collector, and frother are added. The slurry will be then pumped to the pyrite rougher flotation cells. Pyrite Rougher Flotation

Furthermore, Benn et al. proposed the use of rapeseed oil as a selective collector for galena (PbS) recovery against pyrite. A laboratory flotation test using a complex sulfide ore containing Pb, Zn, Cu and Fe sulfides using 240 g/t of rapeseed oil as collector gave a higher recovery of lead, copper and zinc minerals than when typical ...

ROLE OF STARCH AND METABISUPHITE ON PURE PYRITE AND PYRITIC ...

Role of starch and metabisulphite on pure pyrite and pyritic copper ore flotation 41 Mineralogical study also showed that about 50% of ore is formed by pyrite, as a major mineral in the ore. Table 1. Chemical analyses of the samples Compound Pure Pyrite Sample % Pyritic Copper Ore Sample % Fe 42.43 27.65 S 49.40 27.22

USE OF NON-TOXIC DEPRESSANTS IN THE SELECTIVE FLOTATION OF ...

The major sulphide minerals in the ore are chalcopyrite, galena, sphalerite, marmatite and pyrite with corresponding metal amounts of 6.80% Pb, 1.05% Cu and 1.50% Zn, respectively. The ore sample was

The critical importance of pulp concentration on the ...

Apr 01, 2016 · The Qixia orebody is a complex lead–zinc sulfide system with pyrite gangue and minor amounts of copper. In order to improve the flotation results, laboratory scale flotation testing of ore samples taken from this operation was performed. Flotation tests used a sequential recovery protocol for selective flotation of first the lead and thereafter the zinc.

At first, ZnO.Fe2O3 was recovered by magnetic separator, and the grade of zinc concentrate is 14.89% and the recovery is 65%.Next step, zinc sulfide was recovered by flotation, and the grade of ...

Gold Ore Flotation Machineries For Pyrite Ore

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 .

Dispersion effect on a lead–zinc sulphide ore flotation. - CORE

Samples of ore and also of the minerals sphalerite, galena, pyrite, and dolomite were selected for the experiments. Nine types of dispersing agents and six blends among them were employed. A set of three dispersing agents was selected for the lead flotation and another set of three was chosen for zinc flotation.

DE-ZINCING OF LEAD-COPPER SULPHIDE MINERALS FLOTATION

the flotation separation is difficult when lead, cop-per and zinc need to justify concentration into three perfect separate products. Flotation problems in general are due to geological origin; hence, the ore have controlling influence on flotation practice. More specifically, the resultant copper or lead ions

Copper-Zinc ores - Danafloat

The flotation separation and recovery approach is quite similar to the Pb-Zn sulphide separation process. Sphalerite is depressed with zinc sulphate addition to the grind with sodium sulphide as an option for enhancing pyrite depression. Copper is floated in the first differential flotation stage at a 10-11 pH with lime.

Copper-Lead-Zinc ores

As described in the lead-zinc ore processing section, zinc sulphate and metabisulphide sphalerite and pyrite depressants, respectively, are typically added to grinding. Then a Cu-Pb bulk concentrate is recovered with xanthate, dithiophosphate and flotation reagent blends.

Evaluation of the Use of Recycled Vegetable Oil as a ...

ore containing Pb, Zn, Cu and Fe sulfides using 240 g/t of rapeseed oil as collector gave a higher recovery of lead, copper and zinc minerals than when typical, conventional collectors (xanthate, dithiophosphate, mercaptan, etc.) were used. Pyrite recovery in this study was similar to that obtained using the conventional collectors.
