用石硫合剂（LSSS）法从高铅金精矿浸出金

A Lime-Sulphur-Synthetic-Solution(LSSS)Method for Leaching of Gold from High-Lead Refractory Concentrates

石硫合剂法是最新的无氰提金技术。石硫合剂法浸金机理是：电化学－催化机理。本文对石硫合剂法浸出高铅顽固金精矿样的工艺研究表明：石硫合剂法对顽固金精矿的适应性良好，采取二段浸出工艺，金浸出率可达９９％，为国内外大量顽固金矿的开发利用提供了条件和可能途径。

The Lime-Sulphur-Synthetic-Solution(LSSS)method invented firstly in the world is a noncyanic technology of exttaction of gold .The mech- anism of leaching gold by LSSS method is an electrochemicalcatalytical mech- anism.The technical study shows that the LSSS method is more adequate to treating high-lead refractory concentrates bearing gold,and the recovery of gold may reach 99% by using two stage leaching technology.So the LSSS method provides a condition or a possible way for treating a Iot of refractory concentrates bearing gold in the world.
