提高东山选矿厂精矿-200目含量的工业试验研究

Commercial Test Research on Reducing the Concentrate Minus 200 Mesh at Dongshan Concentrator

通过对东山选矿厂 2 0 0 0年改造后的阶段磨选流程影响铁精矿 - 2 0 0目含量的可行性分析 ,提出了实施半自磨工艺和圆筒筛改造方案。现场实施改造后 ,精矿细度由 - 2 0 0目占 6 7%提高到 85 % 。

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.
