摘要
A minerals processing system (200, 300) comprising a flotation circuit (109) is characterized in that a dry grinding circuit precedes the flotation circuit (109). The dry grinding circuit may use a vertical roller mill (32) or roller grinder (302), and at least one dry air particle separation device (201, 304, 307) positioned between said vertical roller mill (32) or roller grinder (302) and the flotation circuit (109). The at least one dry air particle separation device (201, 304, 307) produces a dry fines stream (38) and a dry coarse stream (202). The coarse stream (202) is provided to the flotation circuit (109) to recover metal values, whereas the dry fines stream (38) circumvents the flotation circuit (109) and is combined with dewatered tailings (116) derived from material (110, 111) leaving the flotation circuit (109).
