The requirements for different types of ore dressing equipment, uneven We usually study the mineral composition of the ore mining mill, and also distinguish between the causes and process minerals and other characteristics, the study of the ore is gradually deepening large ball mill, and different ore dressing equipment is not required the same. Under normal circumstances the ore mineral ore and gangue minerals. Ore minerals in ore means can be utilized metal or non-metallic minerals, also known useful minerals. Such as chromium ore chromite, copper ore chalcopyrite, bornite, chalcocite and malachite, asbestos and other asbestos ore. Gangue minerals and ore minerals are those accompanying students, temporarily unable to take advantage of the mineral, also known as useless minerals. Such as chromium ore in the olivine, pyroxene, copper ore sericite, quartz, chlorite, dolomite and asbestos ore calcite. Gangue minerals are mainly non-metallic minerals, but also include some metallic minerals, such as copper ore containing very little galena, sphalerite, because no utilization value, also known as gangue minerals. Weight ore and gangue minerals contained in the ore minerals than the ball, with different metal ores varies. In tandem with the same ore grade ore wealth of different makes a difference. In many metal ore gangue minerals often far exceeds the weight of the weight of the mineral ore. Accordingly, the ore before smelting, subject to beneficiation, most unwanted material is discarded only after smelting. Ore minerals according to the amount of mineral content can be divided into: ① main mineral means more content in the ore, and plays a major role in certain minerals in the mineral; ② secondary minerals, referring to the content of less ore, ore mineral grade is not decisive; ③ trace minerals, ores generally means a low content of the ore minerals can not afford a big role. XJ-type flotation machine features: self-priming air and pulp, easy to implement gravity middling returns, less auxiliary equipment, energy-saving ball mill equipment configuration neat, simple operation and maintenance and so on. XJ type flotation machine is a mechanical flotation machines stir. Mechanical flotation machines are mechanical pulp inflation and stirred by the impeller and a stator consisting of a stirring device is completed, belonging to the outside air self-priming flotation machine, usually the upper part of the gas inhaled, namely in the lower part of the flotation tank intake air near the mechanical stirrer. According to the type of mechanical stirring apparatus can be such a flotation machine is divided into different models, such as the XJ-type, SF type.
