1 概述我国是世界上锌资源较为丰富的国家之一,也是锌主要的生产国。据介绍,从198哇年到1993年,我国锌精矿产量年递增率为11.0%,锌产量年递增率达13.7%。随着汽车业、建筑业、计算机工业、通讯业等产业的发展。锌的用途具有更加广阔的前景,需求量将大幅度增加。赣南除有丰富的钨、淋积型稀土等矿藏外,锌矿储量也很“可观”。赣南的锌矿基本上以硫化物形态赋存,且含铅较低(小于8%),经浮选可使锌精矿中铅降到0.4%~1.2%,这正是火法炼锌生产中较理想的原料。
1 Overview China is one of the richest countries in the world in terms of zinc resources and is also a major producer of zinc. According to reports, from 198 wow to 1993, China’s zinc concentrate output increased at an annual rate of 11.0%, zinc production rate of 13.7% annual increase. With the automotive industry, construction industry, computer industry, communications and other industries. The use of zinc has a broader outlook, demand will increase significantly. Gannan addition to rich tungsten, deposition of rare earth deposits, the zinc reserves are also “considerable ”. Zinc deposits in southern Jiangxi basically occur in the form of sulphide with low lead content (less than 8%). The flotation of lead in zinc concentrates reduces 0.4% -1.2% of the zinc concentrate, which is the result of pyrolytic zinc Production of the ideal raw materials.
