Comminution Circuits for Gold Ore Processing -

2016-1-1  HPGRs first made inroads into diamond processing (where rock fracture along grain lines favored a reduction in diamond breakage during comminution), and in the iron-ore industry. Over the course of the past 20 years, HPGR-based circuits have become a circuit commonly evaluated, and there are now many circuits in operation.

Flotability of metallic iron fines from comminution ...

2008-11-1  The effect of metallic iron fines on froth flotation of a sulfide ore was examined by comparing the flotation results with and without iron fines present in the flotation feed. Mild steel and ceramic laboratory ball mills were used to grind 600 g sulfide ore charges. The mild steel ball mill generated approximately 4.6 g of iron fines (0.8% of the ore charge mass) when grinding to a product ...
