The floatability of copper oxide ores is generally worse than that of copper sulfide ores, and is greatly influenced by the existing form of copper in minerals and gangue composition. For example, when copper is in the form of carbonate (malachite, blue copper ore), the flotability is relatively good, while the flotability of silicate (silica … Read more
Machined sand is relative to natural sand such as river sand. Natural sand is mainly attacked by natural forces, such as river sand, sea sand, mountain sand and so on. Machine-made sand refers to rock particles with particle size less than 4.75 mm made by mechanical crushing and screening after soil removal. Making machine-made sand … Read more
Flotation is a method of wet separation of grinded solid minerals according to the different physical and chemical properties of mineral surface. The flotation method commonly used in industry is essentially froth flotation. It is characterized by the addition of chemical additives to the pulp and the introduction of air. After strong stirring, bubbles are … Read more
In road construction projects, stone is an important building material and is widely used.
