1. Introduction. Wet milling in ball mills followed by flotation is the general practice employed in the beneficiation of copper sulphide ores in which the major minerals of commercial significance typically are chalcopyrite (CuFeS 2), bornite (Cu 5 FeS 4), covellite (CuS) and chalcocite (Cu 2 S). The flotation response of ground minerals can …

Batch flotation tests confirmed that pulp aeration and lime-aid grinding were beneficial to accelerate copper flotation and promote the separation of copper and iron sulfide minerals. At DDP in Anhui, Province, its production situation was unstable, and the recovery of Cu was unsatisfactory which contributed to lots of Cu loss in Cu tailings.

As an essential process before flotation, grinding aims to provide qualified granular feed and high liberation for the subsequent separation [3,11,12]. The grinding cost accounts for more than 50% of the total cost of a beneficiation plant. The grinding cost mainly includes the medium and power consumption costs.

The traditional high alkaline process (HAP) always encounters challenges in handling pyrrhotite-rich type copper sulfide ore, especially the slow copper flotation rate and the unsatisfactory separation efficiency. In this study, HAP was optimized via pulp aeration and lime-aid grinding, and their beneficial effect was studied systematically.
