Title:
GOLD DISTRIBUTION RATE ANALYSIS METHOD OF ORE
Document Type and Number:
Japanese Patent JP2015114240
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a gold distribution ratio analysis method of ore capable of accurately analyzing a gold partition ratio.SOLUTION: A step of performing an alkali exudation after performing an acid exudation or a cyan exudation of an ore sample is repeated while changing the kind of acid or alkali, and a gold partition ratio for each step is obtained by chemically analyzing a filtrate and a residue of each step, and a ratio of mineral species dissolved in an acid or an alkali is obtained by analyzing the mineral residue of each step, and a gold partition ratio for each mineral species is obtained from the gold partition ratio and the ratio of the mineral species for each step. Even when all the intended mineral species are not dissolved in acid or alkali or when the other mineral species are dissolved, the gold partition ratio can be accurately analyzed.
