recovery of silver from lead/zinc flotation tailings by thiosulfate leaching

1. Introduction

Especially old flotation tailings contain more gold content due to overage and inefficient processing methods. The amount of gold in tailings depends on the feed. Flotation tailings from ores contain from to ppm as reported in some works. This constitutes a potential resource for further treatment [9] …

Introduction to Mineral Processing Chevron Phillips Chemical

The tailings from the molybdenum plant are the final copper concentrate (typically greater than 30% copper). Following molybdenum rougher flotation and several stages of cleaning, a final molybdenum concentrate is produced. The final molybdenum concentrate is typically greater than 55%. Lead/Zinc Ore. Lead and zinc often occur in the same ore.

lead, or zinc. Flotation concentrates are usually sent to an offsite smelting facility for recovery of gold and base metals. Cyanide leaching is frequently used in conjunction with flotation. Cyanidation of flotation concentrates or flotation tailings is done depending upon the specific mineralogy and flowsheet economics.

Sodium Thiosulphate Gold Leaching

The gold industry has been seeking alternative reagents for leaching gold from lowgrade ores for the past 25 years. The cost and transport of cyanide, the poor recovery of gold from carbonaceous ores, the lack of selectivity of cyanide towards copper minerals and the cost of waste treatment are real factors which can make cyanide unattractive in some circumstances.
