The separation methods of scheelite are different with different disseminated grain size. For coarse-grained scheelite, generally uses a gravity separation method, which has the advantages of lower cost, less environmental pollution and higher recovery ratio. For fine size scheelite, the separation uses the flotation separation method.
efficient tool for grinding many materials into fine powder.2) The ball mill is used to grind many kinds of mine and other materials, or to select the mine3) widely used in building material, and chemical industry.4) There are two ways of grinding: the dry way and the wet way.5) can be divided into tabular type and flowing type according to differentexpelling mine6) To use the ball mill, the material to be ground is loaded into the neoprene barrel that contains grinding media.7) As the barrel rotates, the material is crushed between the individual pieces of grinding media that mix and crush the product into fine powder over a period of several hours.8) The longer the ball mill runs, the finer the powder will be.9) Ultimate particle size depends entirely on how hard the material you're grinding is, and the time how long the ball mill runs.

Our Black Gold Magnetic Separator was designed specifically for fine gold recovery and it is the most effective gold recovery magnetic separator on the market. But even with this ability, magnetic separation alone cannot solve the miner's challenges.
Additionally, the metal of kings has been used as currency for centuries. The free market has selected it to be used as money for thousands of years, partly because it is transportable, with a high value-to-weight ratio. Its densitymakes it more difficult to counterfeit. It is also fungible in that all gold ounces are worth the same. And it’s divisible, meaning that it does not lose its value just because it is broken into smaller increments. And it’s durable – not corroding or tarnishing over the years. Historically, the first gold coins were made in Anatolia during the 6th century BC. Most modern bullion coins come in 1 ounce, ½ oz, ¼ oz, 1/10 oz, and even 1/20 oz sizes.
Iron can exist in the form of two crystal lattices: a body-centered cubic lattice and a face-centered cubic lattice. Below 910°C, αFe with a body-centered cubic lattice is stable (a = 2.86645 angstroms [Å] at 20°C). Between 910°C and 1400°C, the γ-modification with a face-centered cubic lattice is stable (a = 3.64 Å). Above 1400°C the body-centered cubic lattice of δ-Fe (a = 2.94 Å) forms and is stable up to its melting point (1539°C). Up to 769°C (the Curie point), α-Fe is ferromagnetic. The γ- and δ-Fe modifications are paramagnetic.

The process of concentrating potash minerals, which comprises the treatment of a conditioned, high-density pulp in an elongated, confined zone of substantial vertical extent, moving a high density portion of the pulp progressively along the bottom of said zone from a point of feed introduction at one end to a point of tailings discharge at its opposite end, subjecting said pulp flow to interruptions at a series of stages between feed introduction and tailings discharge in conjunction with an aerating action induced by a high-velocity discharge of an aerating composition into the lower portion of the flow, restricting tailings discharge in accordance with density changes in the pulp at the discharge end of said zone, and removing collected potash mineral concentrate from the surface throughout substantially the lengthwise extent of said zone.
