| Abstract: | Based on the feasibility analysis of influencing the concentrate minus 200 mesh by the staged grinding and separation flowsheet transformed in 2000 at Dongshan Concentrator,a new transformation scheme of semi autogenous grinding technology and drum screens was put forward.Its on site implementation has improved the concentrate fineness from 67% to 85% minus 200 mesh and the concentrate grade and recovery have also been increased. |
