This is because it is common to observe a difference (sometimes significant) between the rod mill and ball mill index values for a given ore type (McKen, Verret, Williams, 2006). On

1. Introduction. For just over a decade now, artisanal and smallscale gold mining (ASGM) in South Kivu province of the Democratic Republic of the Congo (DRC) has undergone a process of mechanisation, challenging the tendency in the literature to portray artisanal and smallscale mining (ASM) as characterised by low levels of capital expenditure and technology usage and high levels of labour ...

The earliest, and simplest method of crushing ore was the use of arrastras. When enough capital was available, stamp mills replaced arrastras at most mines. The following sections take a look at various types of stamp mills, the most common milling facilities at mines of the frontier West. The Trench mill at Silver City, Nevada 1877.

Rod Mills may be considered either fine crushers or coarse grinding equipment. They are capable of taking as large as 2″ feed and making a product as fine as 3548 mesh. Of particular advantage is their adaptability to handling wet sticky ores, which normally would cause difficulty in crushing operations.

Gold has been mined in Scotland for centuries. There was a shortlived gold rush in 1852 at Auchtermuchty and Kinnesswood, and another in 1869 at Baile An Or on the Kildonan burn in Helmsdale in Sutherland. There have been several attempts to run commercial mines. In the Lowther Hills, Leadhills, and Wanlockhead areas gold prospecting and the extraction of lead metal went hand in hand.
