Amorphous graphite beneficiation process The amorphous ore ore grade is relatively high, generally 30% to 90%, but due to the fine grain size of the graphite inlay, it is difficult to improve the grade. There is often no sorting operation for high-grade graphite, and most of China's graphite ore is such. The general process of amorphous graphite beneficiation is: raw ore crushing-grinding-flotation-dehydration-drying-milling-grading-packaging. The crypto-quality graphite ore beneficiation process in Kaisersburg, Austria includes a dry process for direct milling and a flotation wet process (Figure 2). The ore content of the ore treated by the mine is 30% to 80%. Coal flotation using as collector oil, pine oil as a frother and flotation, the slurry pH 8, 90% of the carbon-containing concentrate is eligible to 92%. The dry process produces low carbon graphite.
This category is formate, which includes Calcium Formate, Sodium Formate, Potassium Formate.
