Simultaneous ball milling and leaching by sulfuric acid was applied to enhance copper leaching from copper concentrate consisted of chalcopyrite and pyrite with small amount of bornite.
May 01, 1996 Process. 46 (1996) 205-213 211 Table 3 pH changes on interaction of chalcopyrite ore particles of different sizes with mill water Particle size Initial pH Final pH - 10+30 mesh 11.8 7-8.5 9-10 6-7 -200 mesh 12.6 6.3 11.8 5.2 10.0 5.0 particles can lead to acid formation enhancing ball wear.
This study was aimed to investigate the galvanic interaction between pyrite and chalcopyrite with two types of grinding media (low alloy and high carbon chromium steel ball) in grinding of a porphyry copper sulphide ore. Results indicated that injection of different gases into mill altered the oxidation-reduction environment during grinding.
Dec 01, 2005 A 7.0 g sample of chalcopyrite was loaded into a laboratory scale ball mill (Calka and Radlinski, 1991) along with five 25.4 mm stainless steel balls giving a ball to powder mass ratio of 45:1. After sealing, the mills were evacuated to ∼ 10 − 2 Pa and backfilled with the required atmosphere (argon, air or oxygen).

Bioleaching of a low grade chalcopyrite (ball mill spillage material) was tested for copper recovery in shake flasks. The original samples (as received) were thermally activated (600 C, 30 min) to notice the change in physico-chemical and mineralogical characteristics of the host rock and subsequently its effect on copper recovery.
