Production of apatite concentrate from fine-grain carbonate-silicate technogenic sands

The Kovdorsky GOK JSC increases the production of apatite concentrates by involving fine-grain sands with 10.3–10.5 % P 2 O 5 content from waste piles into the processing flow. The new process and flotationagent mode were developed to produce apatite concentrate with 38.3 % P 2 O 5 content from fine...

Description
Summary:The Kovdorsky GOK JSC increases the production of apatite concentrates by involving fine-grain sands with 10.3–10.5 % P 2 O 5 content from waste piles into the processing flow. The new process and flotationagent mode were developed to produce apatite concentrate with 38.3 % P 2 O 5 content from fine sands with 60–70 % content of −0.071 mm fraction at the recovery as high as 60% P 2 O 5 .
