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.
