Copper Beneficiation Process of Production Status

Copper ore dressing is faced with lower ore quality and difficult to choose compound mining, the increase of the oxidized ore, rising prices of energy and equipment, coupled with the strict environmental protection, lead to beneficiation cost increase, forcing mill plant must be in order to improve the dressing process technical innovation to economic benefits as the center and the application of energy-saving technology, including the main direction of modification is to improve the comprehensive utilization of mineral resources, the recovery of associated gold, silver and molybdenum for the valuable elements such as a high degree of attention.In order to improve the comprehensive utilization of copper ore, mineral intergrowth combined process is the general trend of development.

With the lower ore grade and selection in copper consumption, make the mill plant scale expanding, capacity has reached capacity of mine even more than ten ton per day.With giant construction and expansion, rapid large-scale mineral processing equipment, and to the development of efficient pluripotent, this is the main development direction of current, it can reduce the capital construction investment, can save energy and reduce the processing cost.Another computer system control has been in Canada, Finland, the United States, such as copper mill plant application, respectively in a stable process, improve the effect of indicators to receive.

The Characteristics Of the Copper

Copper is the earliest human use of the metal. Back in prehistoric times, people began mining open pit copper and copper used for making weapons, tools and other utensils style, the use of copper on the early progress of human civilization far-reaching. Copper is present in the earth’s crust and oceans of the metal. The content of copper in the earth’s crust is about 0.01%, in particular copper deposits, the copper content can reach 3% to 5%. The nature of the copper, the majority of compounds that copper minerals present. Copper minerals and other mineral aggregate into copper ore, copper ore mined, after dressing and become a high-grade copper concentrate. Is the only naturally occurring metal in large numbers, but also in a variety of ores (such as chalcopyrite, chalcocite, bornite, cuprite and malachite), the state can be metal and brass, bronze and Other forms alloys used in industrial, engineering and workmanship. Electrical conductivity and thermal conductivity of copper alloy are very good, corrosion resistance is strong, easy processing and tensile and fatigue strength is very good, so the copper was widely used.The application of copper in metal material only is lower than steel and aluminium.Copper in the electrical industry, mechanical industry, chemical industry, defense industry and other sectors with a wide range of uses.

The Copper Beneficiation Process

Copper ore beneficiation process is divided into three steps:

  • Crushing:The basic process of grinding the ore. The original purpose is crushed ore to an appropriate size, suitable mill for grinding part. Ore mined first by the initial jaw crusher broken, broken to a reasonable degree of fineness in the post via elevator, feeder evenly into the ball mill, ball mill and then by an ore crushing, grinding.
  • Grinding:Grinding crushed this step further processing ore with smaller size is to match flotation separation materials.After ball mill grinding of ore fines into the next process: classification.Spiral classifier with different proportion of solid particles in the liquid precipitation rate of different principle of mixed ore washing, grading.After cleaning and grading of the mineral mixture after magnetic separation machine, due to various mineral than susceptibility, through magnetic force and mechanical force will mixture of magnetic materials.
  • Flotation:The importance of flotation process/upgrades copper process.Chemical reagents will be added to the mixer, make reaction.Because of various minerals than susceptibility, through magnetic force and mechanical force will mixture of magnetic materials.After preliminary separation of magnetic separator, the mineral particles are fed into the flotation machine, according to the different mineral characteristics to join different drugs, makes separation of minerals and other substances.
    Desire to minerals is separated out, because it contains a lot of water, must obtain the preliminary enrichment of thickener, then through the dryer drying, drying can be minerals.Copper powder grade up to 45%.
