Crusher an overview ScienceDirect Topics
Crushing is accomplished by compression of the ore against a rigid surface or by impact against a surface in a rigidly constrained motion path Crushing is usually a dry process and carried out on ROM ore in succession of two or three stages, namely, by (1) primary, (2) secondary, and (3) tertiary crushers 13311 Primary CrusherBoth open and closed circuit crushing is employed For close circuit the product is screened with a mesh size much less than the set Figure 64 is a typical setup where ores crushed in primary and secondary crushers are further reduced in size by a rough roll crusher in an open circuit followed by finer size reduction in a closed circuit by a Primary Crusher an overview ScienceDirect Topics By 2000 bc the process of purifying goldsilver alloys with salt to remove the silver was developed The mining of alluvial deposits and, later, lode or vein deposits required crushing prior to gold extraction, and this consumed immense amounts of manpower By ad 100, up to 40,000 slaves were employed in gold Gold processing Britannica
