Abstract

Abstract:

The content of gold of certain gold ore containing high content of arsenic is 17g/t-l8g/t, and the gold ore contains 20.1％- 20.5％ (rnass fraction) arsenic, 18.46％ sulfur and 3.05％ lead, and gold is hardly cyanide leached mainly since parceled up by arsenide and sulphuret. The gold cyanide leaching rate is 56.17％ by direct roasting, but within 81.48％ with addition of auxiliary agent, then reaches as high as 87％- 90％ with addition of 2kg/t leaching agent and improves the velocity of cyanidation as well.

Key words: gold ore, masting, auxiliary agent, leaching agent
