2013-11-8  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.

Silver Lead Zinc Ore Processing Method using Flotation

2016-4-20  Also, the recovery of silver minerals occurring in a lead, zinc sulfide ore is efficiently accomplished using Flowsheet #2. 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

Effect of grinding media on zinc depression in a lead

2009-8-1  Laboratory testwork, investigating the effect of high chrome grinding media in a lead regrind application has on subsequent metallurgical performance, was conducted at a large silver–lead–zinc operation in Australia. The initial data showed that the use of a more inert grinding media could have increased zinc losses to the lead cleaner

LEAD ZINC EXTRACTION PROCESSES [email protected]

2012-7-25  The most important lead ore is galena (lead sulfide). Other important ores such as cerrusite (lead carbonate) and anglesite (lead sulfate) may be regarded as weathered products of galena and they are usually found nearer to the surface. Lead and zinc ores often occur together and for most extraction methods they have to be separated.
