Sample Reduction Mining SGS
The methods for exploration mining and milling were by today s standards rather primitive Examples of good mining practice for underground mines are Diamond drilling is the primary sampling method employed at the mines that so equipment for preparing broken ore samples crushers mills rotary splitters Sample reduction crushing splitting and screening are the steps that ring and puck mills to prepare a smaller particle size if required for sample pulverizing
