Gold is usually found alone or alloyed with mercury or silver but can also be found in ores such as calaverite sylvanite nagyagite petzite and krennerite Most gold ore now comes from either open pit or underground mines The ores sometimes contain as little as 5100 of an ounce of gold per ton of rock
from lead ore saparated gold and silver plant gold ore silver ore copper nickel lead The copperrich solution is then pumped to the solvent extraction plant to separate the copper as a copper complex
Lead ores are usually associated with other metals particularly silver which can be mined at the same time – and zinc which can cause problems during smelting The Sulfide Mineral Galena a Lead sulfide PbS is the most important ore mineral of Lead It can contain 86 Lead
Mining first began in the Gilman area in the late 1870s for gold silver lead and zinc Four roasting and magnetic separation plants used to process the ore until 1919 An underground mill constructed to extract lead and zinc metals operated from 1919 to 1979
particularly silver zinc copper and sometimes gold Thus lead is also a coproduct of zinc copper and silver production making the extraction of lead more economic than if it occurred in isolation Ore Concentration The leadrich ore with a typical concentration range of 38 lead must first be separated from other material the gangue
Lead and zinc ores are usually found together with gold and silver A leadzinc 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 Forms of Lead and Zinc Ore

There are two general classes of silver ore that have been mined 1 leadsilver and 2 highgrade silver ores Both have almost always varying amounts of gold The lead silver mines furnish also as noted above by far the greater portion of the lead produced in the United States
Thus in studying the metallurgy of copper and lead we cover a large section relating to the winning of gold and silver Lead Minerals The lead minerals occur as follows Galena The universal lead mineral is galena PbS which occurs as the main one of all our deposits Lead Carbonate
Lead and zinc ores are usually found together with gold and silver A leadzinc 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 Forms of Lead and Zinc Ore
If the galena contains small amounts of lead gold silver cyanide is advantageous to eliminate the harmful effects of lead cyanide solution of alkali metal sulfide in the Extract argentite AgS the lead salt can make the resulting precipitate as Na2S in S2 PbS thereby promoting dissolution of silver cyanide solution but galena silver sulfate complex can not afford the above effect
Interested in The processes of smelting or roasting your ore to recover its gold and silver Some fairly rich ores require a lot of work to get all the gold and silver out them Historically smelting and roasting of ores have been used to capture the gold from difficult to treat ores
