Highly mechanized mining techniques are followed for the mining the mercury-containing -ores. The process of hydrometallurgy can be executed for obtaining the metal which involves leaching the ores and treating the concentrate with sodium hydroxide and sodium sulfide solutions. Get price

Dangers of Mercury

Traditional mining processes use mercury to amalgamate rocks into precious metals, like gold. The process of separating these elements can lead to excess mercury released as vapor or into the soil itself. It is imperative to use more thoughtful, safe techniques to eliminate the creation of excess mercury during the mining process. Get price
