Mineral Processing Insights

Engineer-written guides on flowsheet design, equipment selection and recovery optimisation for gold, copper, lithium and other ores.

The Xinhai Insights library is written by process engineers to help you make flowsheet and equipment decisions: how to choose between gravity, flotation and leaching; how to size a ball mill; CIL vs CIP vs heap leach; classifier vs hydrocyclone; tailings dewatering; and cost control in cyanidation. Each guide links to the relevant equipment and ore-type solution.

Popular topics: gold processing, grinding, classification, magnetic separation, dewatering. Prefer to talk it through? Ask an engineer.
