(1) Main ore dressing methods for phosphate rock : See Table 1.
(2) Process â‘ flotation - magnetic separation joint process designed primarily for phosphate rock containing iron, titanium and other magnetic mineral. Because less of this type of ore, so far only a few beneficiation plant using.
2 grinding - grading - flotation process
It is used to treat phosphate rock with less weathering or no weathering, ie less clay . The flotation operation depends on the nature of the ore, and the positive flotation method, the reverse flotation method or the positive-reverse flotation method may be used respectively. Most of our concentrators use this process.
3-stage grinding-stage dressing process This process is used to treat phosphate rock ore that exists at the same time as the phosphate rock and apatite. For example, the Ningxia Helanshan Concentrator uses this process.
4 scrubbing - desliming - flotation process
This process is used for phosphate rock ore with severe weathering and high clay content. Due to the small number of such deposits, China is currently only used in a few concentrating plants, such as surface weathering mines around Dianchi Lake in Yunnan.
5 roasting-digestion-classification process This process is used for sedimentary calcareous phosphate rock ore with hard ore and carbonate minerals (dolomite and calcite ). The process is currently in the experimental phase and has not been promoted.
Paper cup making machine is the automatic environmental machine with multi-running positions. This machine runs a whole procedure of paper-feeding, cup-fan-wall sealing, oiling, bottom-punching, heating, rolling, rimming, rounding and tripping. It is the ideal equipment for producing paper cup, tea cup, coffee cup, advertisement cup, ice cream paper cup or other food.
