A phosphate rock containing MgO 7.95% and SiO2 9.64% has fine dissemination size, which is from Yichang city in Hubei province, China. Technical conditions of the ore were investigated by performing reverse flotation, which adopted anion collector to flotate magnesium. The results showed that under H2SO4 3500g/t, H3PO4 2500g/t, MG-2 3200g/t, phosphate concentrate …

The dissemination size of the tungsten ore is extremely uneven, with 0.02~1.28 mm for scheelite and 0.01~1.28 mm for wolframite. The dissemination size of scheelite is coarser than that of wolframite. The size of 83% of scheelite and 60% of wolframite is greater than 0.04 mm. The composition of minerals in the ore is quite complex.

However, it initial iron content in these studies was about 40%, classifying the ores as low-grade and challenging. Owing to the small size of iron-containing mineral inclusions, achieving hematite ore release often requires grinding to the micron level [1, 5]. Beneficiation methods that accommodate such fine raw materials have been developed.
