红土矿比较难处理。铁是其中的主要成分,绝大部分以弱磁性铁矿物存在,一般含铬较高。从红土矿提取镍钴残渣中综合回收铁并降其含铬量是有意义的课题。近十多年来,虽然一些国家对红土矿提取镍钴残渣在用选矿方法回收铁方面进行过一些研究,但目前还没有取得较大进展,更没有较好的工艺在工业上获得成功。本文的研究目的曾是为了解决阿尔巴尼亚缺乏炼铁原料问题和研究合理的工艺流程及条件。通过对红土矿的试验研究,发现了这类红土矿类型的铁矿物在还原焙烧、氨浸

Laterite more difficult to deal with. Iron is one of the main components, the vast majority of weak magnetic iron ore exists, generally higher chromium. Extraction of nickel and cobalt residues from laterite ore comprehensive recovery of iron and its chromium content is a meaningful issue. In the past decade or so, although some countries have done some research on the recovery of nickel and cobalt residue in lateritic mines using iron ore beneficiation methods, no great progress has been made yet, and more and no better industrial success has been achieved. The purpose of this paper was to solve the problem of lack of ironmaking raw materials in Albania and to study the reasonable technological process and conditions. Through the study of laterite, it has been found that the iron minerals of this type of laterite are in the process of reduction roasting, ammonia leaching
