SAG mills, rod mills and ball mills are the classical pieces of grinding equipment employed in gold recovery plants. There is an increasing trend to employ SAG mills (semiautogenous mills) in place of secondary and tertiary crushing and primary grinding. The most common type of rod mill is the overflow mill. There are two typed of ball mills used.

As a natural reduction mineral, pyrite (FeS 2), was combined with biochar by simply ball milling technology to synthesize FeS 2 @biochar composite (BM-FeS 2 @BC) and applied for the removal of hexavalent chromium (Cr(VI)) in aqueous solution. SEM, XRD, FTIR, and XPS characterization results showed that the FeS 2 and biochar were successfully combined and …

The site was first discovered in 1870. The Corta Atalaya-Alfredo Pyrite Mill is a surface and underground mining operation. Initial production took place in 1907. Mine operations consist of 2 distinct surface and underground workings extending 135.00 hectares (333.59 acres). There is one known shaft. The mining method is open pit.
