AMENABILITY OF COLUMN FLOTATION FOR LEAD ZINC BENEFICIATION A CASE STUDY S. Prabhakar and G. Bhaskar Raju National Metallurgical Laboratory (Madras Centre), CSIR Madras Complex, Chennai 600 113, India. Abstract: The amenability of column flotation technology for the beneficiation of lead and zinc was studied by
The ore has first to be separated from clays and other silicates ('gangue') after which the lead ore and the zinc ore are separated. The process used is froth flotation , a succession of stages each delivering a greater concentration of the lead ore.
After carrying out a froth flotation separation, the products are as shown in Table 1. Using this data, calculate: (a) Ratio of concentration (b) % Metal Recovery (c) % Metal Loss (d) % Weight Recovery, or % Yield (e) Enrichment Ratio Table 1: Grade/recovery performance of a hypothetical copper ore flotation process.
flotation scheme adopted for concentration of the lead zinc ore sample consisted of differential flotation separation by depression of zinc bearing minerals using a combination of sodium cyanide and zinc sulphate as depressant and flotation of lead minerals using potassium ethyl xanthate as collector and methyl iso butyl carbinol (MIBC) as frother.

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.
According to the refractory lead zinc ore properties with high pyrite, the experimental studies were conducted on floatation reagent conditions and closed circuit tests for comprehensive recovering of all types useful minerals. In comparison to the test results of different process flowsheets and different types of flotation reagents, adopting prior flotation lead (Pb)Zn selective flotation
Flotation of zinc oxide ore using cationic and cationic anionic mixed collectors 151 Armac C. The increase of both collectors dosage increases Zn recovery and decreases Zn grade in the smithsonite flotation concentrate. The reduction of Zn grade is at tributed to the flotation of more gangue minerals due to high collector concentration. Fig. 6.
In the case of your project, differential flotation to produce separate copper, lead and zinc concentrates would be the likely first choice of flow sheet.

The tailing from the lead flotation circuit is the feed to the zinc circuit. The ability to selectively float the separate minerals depends on the ore, the chemicals, and other factors. Conclusion. Gold, silver, copper, lead, zinc, molybdenum, iron, potash, phosphate, and even sand for glass are often processed by froth flotation.
Option 1: using crude zinc as agent for desilvering during lead refining process. The silver zinc crust is treated by continuous distillation to separate high purity zinc and Ag Pb alloy. The high purity zinc is casted into ingot for sale. Ag Pb alloy is further treated by discontinuous distillation to obtain lead bullion and crude silver.

Lead and Zinc Lead and zinc ores are usually found together with gold and silver. A lead zinc ore may also contain lead sulfide, zinc sulfide, iron sulfide, iron carbonate, and quartz. When zinc and lead sulfides are present in profitable amounts they are regarded as ore minerals. The remaining rock and minerals are called gangue.

The problem of treating oxidized lead zinc ores for the production of high grade lead zinc flotation concentrates is a complex problem due to the nature of the ores and to the soft sliming characteristics of the lead and zinc minerals. The ore for treatment is a lead zinc carbonate ore in a mixed siliceous lime carbonate gangue. The association of
