Phosphorus ore industry type: G.1 divide the main purpose of the industrial type of phosphate rock, as soon as possible in order to get the concept of evaluation of the mining industry, and on the basis of a reasonable arrangement beneficiation and processing test work.
G.2 The selectivity and processing of phosphate rock is related to the type and quantity of phosphorus-bearing minerals and gangue minerals. The former is the basis for the classification of the main types of phosphate ore, and the latter is the basis for the classification of sub-categories.
G.3 According to the structural characteristics of phosphate minerals in ore, the types of ore in China's phosphate deposits can be divided into two categories: porphyritic and microcrystalline apatite-based phosphorite deposits and crystallites. Apatite-based apatite ore and apatite ore. In addition to phosphorus shale rich ore and some medium grade phosphate rock, it is not necessary to directly process and utilize mineral processing. All types of medium and low grade phosphate rock generally need to be processed after mineral processing. New types of phosphate rock (such as aluminum phosphate rock) to enhance processing and beneficiation: Utilization divided ore based on this type of industry.
G.4 The main gangue minerals in phosphate rock include siliceous minerals, silicate minerals, and carbonate minerals. According to its type, content and technical characteristics of beneficiation processing, the phosphate ore is divided into three sub-classes of siliceous and silicate, carbonate and mixed. The content of carbonate minerals (mass fraction) in each kind of gangue minerals are: siliceous and silicate type <30%, mixed type 30%~70%, carbonate type>70%.
G.5 Phosphorite ore (mainly carbonate type and partially mixed type) produces carbonate component loss under weathering, relative enrichment of phosphorus minerals, and changes in gangue mineral composition and ore structure Forming weathered ore. Its ore industry type tends to be siliceous and silicate type, and changes the processing properties of the ore processing technology , and should be divided into weathered ore sub-categories. The weathering type ore discriminant index can be 2 P 2 O 5 mass fraction + A·I ≥ 74% (A·I is the acid insoluble mass fraction), and the CO 2 mass fraction ≤ 5.5%.
G.6 The ore dressing of generalized apatite and phosphorite ore is prone to phosphate rock, and the siliceous ore dressing in phosphorite is prone to silicate type or carbonate type ore, the latter It is also easy to mix ore.
G.7 Phosphorite ore should be sub-classified on the basis of grade. Siliceous or silicate-rich ore is the most ideal raw material for phosphate fertilizer production, while medium-low grade mixed ore is likely to be a direct charge for thermal phosphorus fertilizer. G.8 Ores that have a significant increase in mud content or certain impurities (R 2 O 3 ) that affect processing are to be classified from the same type.
G.9 For some phosphate rock ore with higher associated elements and need to be separated and treated separately, it can also be separated from the same type of ore, with the name of the associated element (such as rare earth carbonate-containing phosphorus). TB).
G.10 ​​When there are two or more useful minerals with different mineral processing characteristics in the ore, the sub-categories may be further classified according to the components they contain, but the participating naming must meet the boundary grade or comprehensive grade specified by the mineral. such as magnetic iron ore apatite.
G.11 The classification of ore industry should be carried out on the basis of the initial delineation of the ore body. When the natural type of ore changes little and regularly, it can also be classified according to the natural type of ore.
Specialized automobile 4s shops lifting platform is a kind of large tonnage car or truck repair and maintenance units commonly used special mechanical Lifting Equipment.
The lifting platform can be divided into upper cylinder lift and lower cylinder lift.
The oil cylinder of the upper oil cylinder Car Repair Lift is placed on the top of the column(with beam), and the oil cylinder of the lower oil cylinder Four Posts Car Lift Platform is placed on the side of the guide rail.
Private car lifts are also often used as great vehicles for moving cars between floors.
