Since the lithium, beryllium, niobium, tantalum or the like sometimes deposits were associated with comprehensive composition, or tungsten, tin and other associated metal deposit and having a comprehensive mining and utilization value, in geological exploration process should be comprehensive evaluation.
The industrial requirements for lithium, antimony, bismuth and antimony ore were formulated in the 1984 "Special Metal Mine Geological Exploration Regulations (Trial)", and the reference industrial indicators for lithium, antimony, antimony and antimony deposits were established (Table 1). 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, strontium, barium, strontium, etc. are sometimes associated with a comprehensive deposit, or associated with polymetallic deposits such as tungsten and tin, and have comprehensive mining and comprehensive utilization value. Comprehensive evaluation should be carried out in the geological exploration process. To this end, the “Indicative Industrial Indicators for Integrated Recovery of Lithium and Lanthanum†was also developed (Table 2.).
