Ore samples, collected from a lead zinc oxide ore deposit in Sichuan province, China, are very difficult to treat with such characteristics as low grade, uneven mineral particle distribution and high containing of slime It is very difficult to separate the lead minerals and zinc minerals, especially for the recovery of zinc oxide minerals On the basis of flotation characteristics study to
The separation of lead, copper and zinc concentrates from the ore sample was achieved using collective and selective flotation methods Prior to flotation tests the ore sample was ground below 200 µ m by controlled screening The metal contents and distributions
Then the tailings were reactivated to separate the zinc concentrate Application Copper zinc polymetallic sulfide ore of similar floatability Advantages Process technology matures easy to control the flotation conditions, combine the strengths of both differential flotation and bulk flotation, widely used in many plants

The flotation reagents can be added in a feed forward fashion based on the plant raw coal tonnage Automatic feedback control of the flotation reagent addition rates has been lacking due to the unavailability of sensors for determining the quality of the froth cell tailings Expensive nuclear based sensors have been tried with limited success
Abstract: The ore is the oxide ore of Copper lead and zinc, The ore has high Oxidation rate of Pb,nearly 50 which contains 3 56 of Pb,3 86 of Zn,0 209 of Cu The flotation flowsheet consisting of the scene is Part of the mixed flotationinhibitor Zn and Pb Cu mix flotationZn flotation
The established lead zinc ore flotation processing scheme is to add zinc sulphate ZnSO4 to the grind to control metal ion activation sphalerite depression Often metabisulphide or other sulphidation chemicals are added with the zinc sulphate for iron sulphide mineral depression a thionocarbamate flotation reagent
A Zinc lead zinc ore dressing plant in Sweden with the daily output of 1000t, Zinc content of 0 58 , lead content of 2 85 and zinc content 4 90 Xinhai adopted Zinc lead mixed flotation Final Zinc concentrate contains Zinc 20 25 and lead 6 75 , and the lead concentrate contains lead 58 73 and Zinc

The process consists of selective flotation to produce a mixed silver, lead concentrate for maximum smelter return and a separate zinc concentrate Over grinding of silver minerals is detrimental to efficient flotation recovery, so the Flash Flotation Unit Cell is used in
Froth flotation is a process for selectively separating hydrophobic materials from hydrophilic This is used in mineral processing, paper recycling and waste water treatment industries Historically this was first used in the mining industry, where it was one of the great enabling technologies of the 20th century
The flotation behavior of the individual minerals is different from that of either leadzinc or copperzinc ore and therefore the treatment process is tailored based on the processing characteristics of the individual ore types Handbook of Flotation Reagents:
Typical lead copper zinc sulphide minerals were found hard to be separated selectively by froth flotation in the plant practice operation due to part of sphalerite was progressively entrapped into lead copper bulk flotation A series of de zincing on lead copper flotation tests has been conducted in the laboratory to reduce unwanted zinc content
