reverse flotation of pyrite from a zinc in georgia

Oct 01 1995 · A mobile flotation facility based on two 5 L minicells equipped with online monitoring of pH dissolved oxygen and pulp potential was used to study flotation of pyrite from zinc concentrate ie reverse flotation at the Trout Lake circuit of Hudson Bay Mining and

Jan 01 1989 · Without the reverse pyrite flotation circuit the conventional zinc flotation circuit could maximize its efficiency at 71 by attaining 505 grade and 83 recovery However if 49 grade could be maintained in the conventional zinc circuit the reverse pyrite flotation circuit could achieve a final zinc concentrate grade of 546 at 82 recovery

reverse flotation of pyrite from a zinc Share On Flotation of Pyrite Sodium silicate was somewhat effective in causing a differential or selective flotation of copper as chalcopyrite from pyrite by keeping pyrite from floating Sodium hydroxide and sodium sulfide gave in most cases a distinct separation of sphalerite from chalcopyrite

process of flotation and separation of fluorite in georgia There are forty years of manufacturing history with three major production basesover 160 senior RD engineers and 600 large and mediumsized digital processing equipment The firstline technicians and professional aftersales service personnel up to 2300 and 200 respectively

Jun 01 2001 · 1 Introduction 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 1962 Voigt et al 1994

of carbonaceous pyrite in copper flotation depression of lead in leadcopper bulk separation Bulatovic 2007 and depression of hematite and apatite in their reverse flotation against siliceous minerals Lin and Burdick 1988 Dextrin dosages of up to 1400 gMg is reported

In the flotation of copper ores several processing plants report that copper recovery is affected by the proportion and type of pyrite in the ore with the effect becoming more intense when the feed ore particles are fine ie in fine regrinding In this work a model mix mineral system consisting of chalcopyrite and pyrite with varying pyrite content in the range 2080 wt was used to

In cases of greater iron sulphide depression challenges the zinc concentrate can be cleaned by reverse flotation of the concentrate by first treating with SO2 to reduce pH to 555 and then heating the pulp to 6070 degrees C The gangue is floated with the sphalerite reporting tothe tails

A mobile flotation facility based on two 5 L minicells equipped with online monitoring of pH dissolved oxygen and pulp potential was used to study flotation of pyrite from zinc concentrate i

The flotation plant design was based on extensive benchscale testwork including locked cycle tests on drill core and many months of operation of a 30 tonne per hour “pilot plant” using the old Cleveland Tin Mine process plant modified for the duty
