Increasing Extraction Efficiency Using a Closed Grinding ...
The solution studied was a Closed Grinding Circuit, which aims to control particle size by sieving the mill product at 590 μm, returning the oversize to grinding. This improves digestion efficiency, since smaller particles react faster and suffer less shortcircuits. This work describes the study and estimated gains, along with tests conducted to prove the residence time distribution and ...
Ball mill media optimization
circuit efficiency is increased and overgrinding is decreased. The other factor that determines overall circuit efficiency is how well the power that is applied to the coarse material grinds it. This is affected by design and operating variables like the media sizing and mill percent solids. From circuit functional performance (McIvor et al., 1990): Circuit production rate of new fine material ...

The Process
A CIL circuit was later added to enhance gold production. Three decades had passed before TT Reclamation acquired the Brakpan plant in 2007 with the aim of reestablishing the Ergo project. During this period, many variables had changed, including the closing of the flotation circuits at all plants. The Brakpan plant was therefore reestablished using CIL.
