The invention discloses a beneficiation method for scheelite. The beneficiation method comprises the step of floating scheelite by taking oleic acid as a collecting agent and a foaming agent under the condition that the PH value of ore pulp is equal to or larger than 10.8. By using the method, the scheelite can be beneficiated at high yield.

The characteristics of Huimin high phosphorus limonite ore and the beneficiation of this iron ore by sodiumcarbonateadded carbothermic reduction, ultrafine grinding and magnetic separation were investigated.
Siderogel is a naturally occurring colloidal form of iron(III) oxidehydroxide. Goethite and lepidocrocite, both crystallizing in orthorhombic system, are the most common forms of iron(III) oxyhydroxide and the most important mineral carriers of iron in soils. Iron(III) oxyhydroxide is the main component of other minerals and mineraloids:
