Our zinc and lead business combines world class assets with global marketing reach and expertise. We mine and process zinc and lead ores in the key mining regions of Australia, South America, Kazakhstan and Canada. And, we smelt and refine zinc and lead at processing operations in Australia, Canada, Spain, Italy, Germany, the UK and Kazakhstan.
The development and application of the new technology of bottomless pillar deep hole mining method has greatly increased the mining production capacity, realized the Mechanization and automation" in Fankou Mine, which helped the production of the mine to reached 180,000 tons of lead and zinc metal successfully, and realized the high and stable production, and high profit.
Lead and zinc concentrate processing. Processing steps used to produce the lead and zinc concentrates include comminution, flotation, leaching and dewatering. Waste water is pumped to a tailings dam with the flotation overflow. The overflow from the lead concentrate thickener is recycled to the lead flotation circuit.
6.1.1 Lead and Zinc Ore Mining Lead and zinc ore is nearly always mined below the surface of the ground. Some veins of ore lie as deep as several thousand feet but most deposits lie close to the surface. Lead and zinc ore is mined almost exclusively in underground operations, though a few surface operations do exist.
Delivered steady state production: Produced 7.7 million ounces of silver, 24.0 million pounds of lead and 8.4 million pounds of zinc in 2019. Chinchillas Pre Feasibility Study Highlights: Long mine life: Average annual silver equivalent production of 8.4 million ounces
Project Overview. Located at Lawn Hill, 250km north west of Mount Isa in the Lower Gulf of Carpentaria, the Century mine began open pit production in 1999. During its initial 16 years of operation, Century was one of the largest zinc mines in the world, producing and processing an average of 475,00tpa zinc concentrate and 50,000tpa lead ...
