卡里布块状硫化矿矿床位于加拿大新不伦瑞克巴瑟斯特以西30公里。有用金属为铜、铅、锌和银。本文所讨论的矿石说明,在黄铁矿基质中细晶粒矿化作用导致选矿工艺复杂化,从1970年一直到1974年断断续续处理过一个较小的次生矿床(3..5％Cu,2.6％Zn,1.1％Pb和59.6克/吨Ag),生产出铜粗精矿。此外实验室试验的目的在于改进可开采的原生矿床(6.2％Zn,2.9％pb,0.3％Cu和85.9克/公吨Ag)的选矿工艺。半工业性浮选试验于1981年中进行的。后来完成了自磨和半自磨半工业性研究计划,并列出了两项研究的结果。
The Caribu massive sulphide ore deposit is located 30 kilometers west of Bathurst, New Brunswick, Canada. Useful metals are copper, lead, zinc and silver. The ores discussed in this article demonstrate that the fine-grained mineralization in pyrite matrices has complicated the beneficiation process, with a minor secondary deposit (3..5% Cu, 2.6% Zn, 1.1% Pb and 59.6 g / t Ag) to produce crude copper concentrate. In addition, the purpose of the laboratory tests is to improve the beneficiation process for mined primary deposits (6.2% Zn, 2.9% pb, 0.3% Cu and 85.9 g / metric ton Ag). Semi-industrial flotation tests were conducted in mid-1981. Later, a self-abrasive and semi-self-abrasive semi-industrial research program was completed and the results of the two studies were listed.
