摘要
本文提出了一种新的铜的化学物相分析浸取剂,以EDTA—TTHA—氯化铵浸取自由氧化铜,可在大量辉铜矿存在下将赤铜矿完全浸取。将硝酸铁引入酸性银盐中,有效地提高了斑铜矿的浸取率,结果与氰化钾法吻合。
A new procedure is performed for the chemical phase analysis of copper. Cuprite, chessylite and malachite are leached by a new solvent (at pH =2.5-3.0) that is the mixture of EDTA and TTHA and NH4Cl. Cuprite is entirely dissolved when larger amount chalcocite is present. Ferric nitrate is added into the silver nitrate as a solvent so that leaching percentage of the bornite is raised. Chalc-opyrite is not dissolved. The result of the test is as good as that of the potassium cyanide method.
