mineral processing technology and mineral processing equipment

Beneficiation Processing of Iron ore Sinonine deeply know that most prominent ore found in world are mainly hematite and magnetite. Among these, hematite is considered to be most important. Iron ore is used in production of pig iron which is further used in production of steel other uses of iron ore are like industrial finishes, polishing compounds and sponge iron industries. Iron ore belongs to Precambrian stage and its deposit is present in massive, laminated, friable and also in powdery form. Hematite Hematite is most important iron ore mineral main source for industries. Its composition is Iron Oxide and sometimes slight amount of titanium. Its name comes from the Greek word for blood, haima, because of its reddish colour. Crystals occurs in thin plates, as well as bundles of small micaceous plates, and in thin splinters. Most commonly massive, mammilary, botryoidal, reniform, oolitic, stalactitic, and radiating. Scalenohedral and rhombohedral crystals occur, although infreq

The mine ores are invariably pulverized to a size small enough to liberate mineral particles from the barren rock (gangue). This comminution is ordinarily the first step that takes place within the mineral processing plant. A number of grinding mill types are employed for mines. The classic grinding circuit consisted of a rod mill followed by a ball mill(s) in a two-stage circuit. This arrangement is still found at older installations and some newer ones that were built with used equipment. A Semi-Autogenous Grinding (SAG) mill followed by a ball (or sometimes a pebble) mill(s) is the common arrangement found in modern plants of medium to large size in North America. Smaller mines often employ an extra stage of crushing to create product small enough to permit single stage grinding with a ball mill(s). Ball Mills The ball mill remains the most widely used grinding unit at hard rock mines. The drum of a primary ball is typically cylindrical and of length equal to or up to 65%

At mines, numerous methods are employed to separate and concentrate the ore (beneficiation). The most common methods are flotation, leaching, gravity separation, and solvent extraction. The most widely employed is flotation. For ores of many metals, flotation is used exclusively, for some it is employed in conjunction with another method, most often gravity separation. The most common application for precious metal ores is leaching. Solvent extraction is usually peculiar to uranium ores and copper oxide ores. This chapter further describes flotation, leaching of precious metals, and gravity separation. Solvent extraction is dealt with only as it relates to the recovery of copper. Flotation Due to surface tension, a tiny flake of gold can float in a glass of water despite the fact that gold is almost twenty times as heavy as water. If the water is stirred vigorously with a spoon after a few drops each of pine oil and creosote (reagents) are added, a minute (<75 m ) gold partic

Sinonine ’s R&D team continuously upgrade and improve beneficiation automation system. According to such characteristics in the entire mineral process as complicated working condition, nonlinearity, variable time lag and multi-variable coupling, the Auto-control System for the Entire beneficiation plant, through synergic control over the key variables in a beneficiation plant, generally reduces the production costs in a beneficiation plant and increases the production benefits with such a result as general benefits being higher than the benefits obtained from the independent control over the variables in different processes in the factory. It is one set of automatic optimization system with high adaptability and has had numerous successful cases in mineral natures as magnetite, copper ore, gold ore, molybdenum ore, nickel ore, bauxite, graphite ore, lead-zinc ore, etc. System characteristics 1.Detection, display and control of many key parameters make the system more accurate

After detailed investigation and research with  the beneficiation test report provided by the research institute, Sinonine’s Henan 500TPD Potash Feldspar Beneficiation team finally made solutions . The production process we designed is crushing, screening, grinding and so on   Crushing & screening circuit : Ore crushing adopts two stage crushing with single closed circuit stage, particle size of ore decreases from 250mm to -15mm. Grinding & classification circuit: Using two stage closed circuit grinding, primary grinding consists of grinder and spiral classifier, its grinding fineness is -0.74mm and accounts for 60%; secondary grinding consists of grinder and spiral classifier, its grinding fineness is -0.74mm and accounts for 80%.   Separation circuit: first-class and second-class ore of particle size -15mm pass a low-intensity magnetic separation and a strong magnetic separation, the concentrate is first-class and second-class frit; first-class and second-class
