KEYNOTE: HPGR in Gold Leach Applications – an .Traduire cette page

Although HPGR's major benefit to hydrometallurgy is its micro-fracturing of the rock matrix, it does generate some finer product sizes which are inherently beneficial for gold heap leaching. This fines generation effect does not constitute a problem for other leach applications, specifically heap leaching of copper ores. Extensive testing between 1996 and 2016 has documented that HPGR ...
