科拉半岛东北部凯依夫斯基山区发现和探明了30多个兰晶石矿床。这些矿床中既有兰晶石呈辐射条状、纤维束状等细粒嵌布的矿石,也有兰晶石呈球状,椭球状(截面达30～50毫米以上)的结核体。对各种兰晶石矿根据其结晶特性,拟订了若干用以获得合格兰晶石精矿的工艺流程方案。各流程都离不了浮选。浮选既用于处理原矿,又用于处理重选的中间产物。兰晶石浮选可以用脂肪酸的乳化剂,其组成为:30％蒸馏塔尔皂,30％饱和合成脂脂酸C_(10)～C_(16)的部
More than 30 lanolite deposits have been discovered and proven in the Kaifuji Mountain in northeastern Kola Peninsula. In these deposits, there are both nodular ores of radiant bands and fiber bundles, as well as nodules of spheroidal or ellipsoid (cross-section of 30-50 mm). A variety of lan-stone quarries according to their crystallization characteristics, to develop a number of qualified lan-stone concentrate process program. Each process can not be separated flotation. Flotation is used both for the treatment of raw ore and for the treatment of re-elected intermediates. Lan Yuanshi flotation can be used fatty acid emulsifier, which consists of: 30% distilled tal bar, 30% saturated synthetic fatty acid C_ (10) ~ C_ (16) of the Department
