阿夫利勘德选矿厂曾对卡乌拉(贝辰加地区)和日丹诺夫斯克两矿床的浸染硫化铜-镍矿石进行了球磨磨矿和矿砾磨矿的工业性比较试验。卡乌拉矿床的矿石与日丹诺夫斯克矿石比较,其侵入岩的变质作用较强:橄榄岩不仅完全变成了蛇纹岩(没有橄榄石残余),而且普遍受到水热变质作用——强烈发育的滑石化及伴随着矿石交代作用的绿泥石化(表1)。
The Avpyé de Contreras has conducted industrial comparative tests of ball-milled and mineralized cuprock-nickel ores with dip-sulphide-nickel ores impregnated in the two deposits in the Kaula (Bechencá) and Ziyanovsk deposits. The metamorphic action of the intrusive rocks in the kawara deposit is stronger than that of the Zhidanovsk ore: the peridotite not only becomes completely serpentinite (without peridotite remnant) but is also generally subject to hydrothermal metamorphism - strongly Developmental talcification and chloritization accompanying ore metasomatism (Table 1).
