Cone and quartering in mineral processing?

Answer 1

Cone and quartering is a sample reduction technique used in mineral processing to obtain a representative sample from a larger bulk sample. The process involves dividing the bulk sample into four equal parts, then removing two opposite quarters and combining the remaining two quarters. This method is repeated as necessary to achieve a smaller, manageable sample size while maintaining its representativeness. It is commonly used to ensure accurate analysis and testing of mineral content.
