Gold processing, preparation of the ore for use in various products.. For thousands of years the word gold has connoted something of beauty or value. These images are derived from two properties of gold, its colour and its chemical stability.The colour of gold is due to the electronic structure of the gold atom, which absorbs electromagnetic radiation with wavelengths less than 5600 angstroms Sep 29, 2017Stamps were used in California gold mines around 1850. First developed in England and used by Cornish miners, stamps were heavy iron machines used to pound rocks containing gold quartz into a fine dust so the gold ore could be extracted. Small stamps were commonly powered by water wheels while larger ones ran by steam engines.

Rod mills, how they function

The rods grind the ore by tumbling within the the mill, similar to the grinding balls in a ball mill. To prevent the conditions leading to rod charge tangling, the length to diameter ratio is maintained at 1.4 to 1.6. Rod mills accept feed up to about 50 mm (2 in.) and produce a product in the size range of 3000 to 270 mm (–4 to –35 mesh).
