What is the role of arsenic in the mining industry - Mining Facts Org

The gold was released from the ore by roasting it at high temperatures, which gave off an arsenic-rich gas. [29] Initially, the arsenic was released directly into the environment, but in 1951 a Cold Cotrell Electrostatic Precipitator was installed which removed much of the arsenic trioxide dust from the air. [28] A Dracco...
