引言南非地区从威特瓦特斯兰德型的前寒武纪砾岩中选出的许多种黄铁矿精矿,都含有相当数量的金,还含有铀以及诸如铜、钴和镍基底金属。根据多年来在焙烧这些精矿以生产硫酸方面所取得的经验,了解到焙烧条件对从焙烧产品中提取金的影响。但却不了解焙烧条件对从焙烧产品中浸出铀和基底金属的影响。

INTRODUCTION Many types of pyrite concentrate from the Wittlandstein-type Precambrian conglomerate in South Africa contain significant amounts of gold, as well as uranium and metals such as copper, cobalt and nickel base metals. Based on years of experience in roasting these concentrates to produce sulfuric acid, the effect of roasting conditions on the extraction of gold from roasted products is known. However, the effect of roasting conditions on the leaching of uranium and base metal from roasted products is not known.
