bulk sampling for Gold ore processing

  • Bulk Sampling in Gold Exploration Supporting Yukon Gold

    Dec 25, 2018· The role of bulk sampling in the gold exploration process. The most important question bulk sampling can answer is whether or not mining a prospective deposit would be both feasible and profitable(PDF) Bulk sampling of complex gold deposits material,Jan 01, 2008· The approach to sample processing will be governed by the results of metallurgical testing and geological knowledge. Careful design of sampling protocols must be undertaken through material.

  • Bulk Sampling of Complex Gold Deposits Material

    Complex gold deposits are generally characterised by variable geometries, strong structural controls on grade distribution and a high-nugget effect. The use of diamond drilling and fire assays in this environment often results in an understatement of grade. Bulk samples are likely to be the closest estimators of true grade, and may be required to evaluate geological/grade risk during resource(PDF) Sampling A critical component to gold mining,Jan 01, 2007· A modified approach to the implementation of Gy's sampling theory is discussed and used to design a procedure for sampling crushed gold ore feed to metallurgical process plants.
