Industrial requirements for rare metal lithium, antimony, bismuth and antimony ore
Lithium, beryllium, niobium, tantalum ore industry requirements, "rare metal mine geological exploration specification (Trial)", the development of the lithium, beryllium, niobium, tantalum deposit industrial index reference issued in China in 1984. Among them, lithium, beryllium cutoff grade and industrial grade mineral deposits are divided into stone hand and machine ores, and were determined grade index. Hand selection and machine selection ore division, according to production practice experience, if the spodumene particle size in the ore body is >3cm, the ore grade is above 2%~3%; the beryl particle size is >0.5cm, the ore grade is 0.1%. ~ 0.2% or more, suitable for hand selection, divided into hand-selected ore, and hand-selected mineral reserves calculation. Niobium, tantalum iron ore particle diameter> 0.3cm, in the mining process may be included with hand-selected. Hand-selected ore tailings are machine-selected and not suitable for hand-selected ore, all of which are machine-selected ores. Lithium, tantalum, niobium, tantalum, etc. are sometimes associated with each other to form a comprehensive deposit, or associated with polymetallic deposits such as tungsten and tin , and have comprehensive mining and comprehensive utilization value, and should be comprehensively evaluated in the geological exploration process.
