Recovery of pyrite from copper tailings by flotation

Sep 01, 2019The cleaner concentrate will be fed to a recleaner stage and the cleaner tailing with a 10% pyrite grade will be recirculated to the rougher stage. The pyrite flotation in the recleaner stage is faster than in the cleaner stage. Get price

Understanding The Critical Relationship Between Reverse

Apr 28, 2014Q f. = feed flow Q p = permeate flow and Q c = concentrate flow. If a system feed flow (Q f) is 1,000,000 gallons per day (GPD) and the permeate flow is 750,000 GPD, then the calculated recovery rate would be 0.75 or 75 percent. 750,000 permeate GPD Get price

pyrite flotation flow

Collectorless flotation of oxidized pyrite - ScienceDirect.

Gold Leaching of Pyrite Concentrate The ore consisted of quartz in which above the 250ft level the ironminerals were largely oxidized and some free gold was visible below that level few traces of oxidation occurred and pyrite constituted the principal mineralizer in the quartz together with occasional pockets of galena and a few eccentric specks of covellite Get price

Pyrite Processing

Aug 26, 2019The process is suitable for pyrite with uneven grain size or friable brittleness. The combined gravity-flotation process is generally rough grinding and classification of raw ore. The separation is carried out by using suitable gravity separation equipment to obtain a part of pyrite concentrate. Get price

The mining process

The reagents help us to separate the valuable mineral content from waste rock and iron sulphide particles like pyrite – or fools gold. Air is forced through the slurry creating bubbles, which float to the surface and attract and bind to the copper particles. Copper concentrate is fed into the ISASMELT furnace, where it is heated to 1185 Get price

Tailings thickener retrofit, OK Tedi

The pyrite concentrate containing sulphur report to a 40m concentrate thickener, namely thickener 1. The tailings from the Pyrite recovery plant reported to two 50m Dorr Oliver conventional thickeners, both of which were to be retrofitted and upgraded. The retrofit and upgrade was to improve the settling rates of solids in the thickener. Get price

Optimising the Telfer Pyrite Regrind Circuit

Evolution of Size and Chemical Composition of Copper

Jan 31, 2018Because both chalcopyrite and pyrite were highly liberated in the concentrate, little interaction between both phases was expected. It is noted that reactions [ 1 ] and [ 7 ] to [ 11 ] involve the loss of sulfur from the particles, whereas reactions [ 10 ] and [ 11 ] produce species with magnetic properties, i.e., cuprospinel (CuFe 2 O 4 ) and Get price

How to Calculate Percent Recovery and What Affects it in a

The concentrate flow is varied by changing the position of the concentrate valve. Generally water temperature and TDS remain fairly constant day-to-day and as a result very little variation in operating flow rates and pressures should be seen. Over a longer term, variations in feed temperature, feed TDS and any membrane fouling effects may Get price
