The following circuits are common in the gold industry: ... 2006). A variant of this method is to direct pebble-crushing circuit product to the ball-mill sump for secondary milling: while convenient, this has the disadvantage of not controlling the top size of feed to the ball-mill circuit.
Stages 1 and 2: Bashing and Mashing. Traditionally, the process selection choice was between a conventional, well-tried, three-stage crushing circuit followed by ball-milling, …
How HPGR improves gold recovery. There are two main ways mines recover gold ore from the gangue, and HPGRs can assist with each process. One of them is heap leaching and for mines using this process, we've found that the most efficient setup is to have a HPGR perform tertiary grinding immediately prior to recovery, completely avoiding the use of a …

The selection of the right crushing equipment for a specific application is influenced by many factors some of which are upstream of the crushing plant (blasting pattern and mining method) and others which are downstream of the crushing plant (heap leach or mill, grinding circuit selection).
optimization. Pustynnoye Gold Mine's crushing circuit includes a jaw crusher and two secondary cone crushers operating in closed-circuit with classification screens. The grinding circuit consists of a semi-autogenous (SAG) mill with a pebble crusher followed by two ball mills. The SAG mill is unusual, with a low aspect ratio similar to
The processing circuit will include three-stage crushing, utilizing the existing Cerro Pelon crushing circuit, and two primary ball mills. One of the ball mills will come from Island Gold as the mill will be decommissioned in 2025 with ore from Island Gold to be fed through the larger Magino mill.
