Abstract:

Heap leaching is an effective method to deal with low grade gold ore.However，the ores containing much fines and clay are not suitable for direct heap leaching.In order to improve the permeability of ore heap，granulating and pretreatment are necessary.Granulating pretreatment can greatly enhance the gold leaching process and in most cases the leaching rate of the gold can also be improved.The issue researched the granulation of refractory gold ores on laboratory-scale condition.Rock ore and fine ore particle are mixed to granulation，using the cement，gypsum，bentonite，polyacrylamide and lime or several of the bond selection agents as binder.More groups of experiment were carried out，and eventually got the granulation adding appropriate cement，lime and polyacrylamide have better comprehensive performance，and the suitable grain size ratio of ore and powder mine is 1∶2，the most suitable water quality is 140~160 mL/kg.Due to the leaching strength of granulation adding gypsum binder is very poor，it’s not suitable for use as a binder.

Key words: refractory gold ores, granulation, adhesive, cement
