In deposits mined today, lead is usually found in ore which also contains zinc, . commonly occur in the near-surface weathered or oxidised zone of a lead orebody.. Lead pipes, water tanks and weights for fishing nets were used in ancient.
Used as a hardening alloy for lead, especially storage batteries and cable sheaths; .. conductivity purposes in flat panel devices - most commonly in liquid crystal . Used in lead-acid batteries, gasoline additives (now being eliminated) and tanks, .. Zinc dust used for primers, paints, precipitation of noble metals; removal of.
copper, nickel-cobalt, zinc-lead, gold-silver and platinum group element (PGE) . Tank leaching techniques have been widely used in mining for the recovery of.
Modern lead mines produce about 3 million metric tons of lead annually. Therefore much lead ore is obtained as a byproduct of other metal mining, usually zinc or silver. First, the finely crushed ore is diluted with water and then poured into a tank . For example the lead commonly used in car batteries, and also for pipe,.
