Using Ball Mills to Extract Raw Gold from Ores

From the ball mill, the gold ore powder is subjected to the process known as beneficiation for further crushing before classification and floatation processes. Most commonly, professional mining operations will use a shaker table at this point.

Gold processing 101 Mining Magazine

Traditionally, the process selection choice was between a conventional, well-tried, three-stage crushing circuit followed by ball milling, or single-stage crushing followed by a semi-autogenous (SAG) mill and ball mill.

Ore processing Waihi Gold

The ball mill is very similar to the SAG mill, except it has a larger proportion of steel balls to assist in the grinding process. Following grinding in the ball mill, the material is returned via the sump (8) to the secondary hydrocyclone (9) for resizing.
