Flotation plant is widely used in various fields of ore dressing industry. For example, the separating of gold ore, silver, galena, sphalerite, chalcopyrite, chalcocite, molybdenite, pyrite, nickel sulfide mineral, malachite, cerussite, smithsonite, he

Gold ore whose types of deposits are diverse and complex is the mineral assemblage of gold. With features of chalcophile affinity and high melting point, the gold ore includes conglomerate type, porphyry type, quartz vein type and volcanic rock type, etc.

Mining copper About 200 years ago the UK was an important world source of copper and tin and there were mines in Cornwall and Devon These mines have now closed and today the biggest copper mines are in Chile Escondida mine and Indonesia Grasberg mine These produce many millions of tonnes of copper ore per year

Copper processing is a complicated process that begins with mining of the ore less than 1 copper and ends with sheets of 9999 pure copper called cathodes which will ultimately be made into products for everyday most common types of ore copper oxide and copper sulfide undergo two different processes hydrometallurgy and pyrometallurgy respectively due to the different

The method was not satisfactory and was discarded for stopes and pillars although very little mining is done by this method because the ore will be handled by steam shovels The Boston Consolidated mine now called the Boston mine of the Utah Copper Co was originally laid out into stopes and pillars Fig 9 illustrates the method
