含粗粒金矿石品位分析试样的加工制备

Sample Processing for Gold Determination in Ores Containing Coarse Grained Gold

摘要: 本文介绍了加工制备含粗粒金矿石的分析样品。对矿石含金品位低、脉石矿物硬度比较小类型的金矿全巷大样,在加工制样中筛上收>0.5mm大粒金。粒度<0.5mm矿石经缩分取样,用重选(摇床)富集粗粒金,分别检测结果,最终计算矿石总含金品位。实践表明,经本法加工试样检测结果所计算的金品位具有可靠性。

Abstract: A procedure is devised for the determination of gold in low grade ores which contain coarse grained gold and low hardness gangue minerals. The gross sample as a whole is crushed to pass a 0.5 mm sieve. The remains on the sieve are examined under a microsc
