mining techniques of lead ore

Lead Mining Concentration process, flotation, filtering Mining the ore : The first step requires the lead ore to be mined from the grounds. Heavy machinery is used to drill the rocks from deep tunnels or blast it with dynamite, breaking the ore into pieces. The ore is then shoveled onto loaders and trucks and hauled to a shaft. Lead Mines an overview ScienceDirect TopicsThe principal method of extracting lead from galena, which is its most prominent ore, is done by pyrometallurgical method of
