一、概述我矿所处理的矿脉是含钽铌伟晶岩脉风化壳矿床,其特点是原矿品位低、嵌布粒度细、矿石组分复杂。其细泥产率大、品位高、粒度细、矿物组成复杂。通过生产实践和多次考查测定,我矿综合细泥量占原矿的20%以上,钽铌金属含量为原矿金属量的20～27%左右,其细泥品位比原矿品位略偏低,而粗选尾矿中细粒级的钽铌品位大都接
I. Overview The veins processed by mine are tantalum-niobium-bearing pegmatite weathering crust deposits characterized by low ore grade, fine grain size distribution and complicated ore components. Its fine mud yield, high grade, fine grain size, complex mineral composition. Through the practice of production and multiple tests, the total amount of fine silt in mine accounts for more than 20% of the original ore, the content of tantalum and niobium metal is about 20-27% of the original ore, the fine mud grade is slightly lower than the raw ore grade, Tailings in the fine-grained grade tantalum niobium grade most access
