干旱地带砂矿地质—工业类型的划分是建立在具附加标准(考虑其工业开发特点)的形态分类基础之上的。这里指的是含较粗粒金的砂矿,金粒可按现有的重力工艺流程用传统的设备提取。 在俄罗斯和独联体范围内,包括南贝加尔沿岸地区、赤塔州的南部、南哈萨克斯坦和中亚等国中纬度的干旱地带,确定了以下具有工业意义的砂金矿成因类型:残积—坡积型占6％;冲积—坡积型占15.5％;冲积型占66％;洪积扇(洪积)型占12.5％。此外,还有暂时没有工业意义的风成型。
The geology-type division of the sandstones in arid zones is based on the morphological classification of additional criteria (taking into account the characteristics of their industrial development). Here refers to the coarse grained gold ore, gold particles can be gravimetric existing existing processes using traditional equipment. The middle-latitude arid regions of Russia and the CIS, including in the coastal areas of South-Baikal, southern Chita, southern Kazakhstan and Central Asia, identify the following types of gold-bearing sands that are of industrial significance: Residual- Alluvial-plateau type accounted for 6%; alluvial-slope type accounted for 15.5%; alluvial 66%; alluvial fan (alluvial) accounted for 12.5%. In addition, there is a wind that has no industrial significance for the time being.
