Copper ore processing introduction

Copper ore is really a chemical element with the symbol Cu (through Latin: cuprum) and atomic number twenty nine. It is a ductile metal with quite high thermal and electrical conductivity. Pure copper is soft and malleable; an exposed surface has a reddish-orange tarnish. It is used as a conductor associated with heat and electricity, a building material, and a constituent of various metallic alloys.

The metal and it is alloys have been used for a large number of years. In the Roman era, copper was principally mined on Cyprus, hence the origin of the name from the metal as сyprium (metal associated with Cyprus), later shortened to cuprum. Its compounds are commonly encountered because copper (II) salts, which often impart blue or green colors to minerals for example turquoise and have been widely utilized historically as pigments. Architectural structures built with copper corrode to provide green verdigris (or patina). Decorative art prominently features copper, both by itself and as a part of pigments.

Copper ions are water-soluble, where they function at low concentration as bacteriostatic substances, fungicides, and wood preservatives. In sufficient amounts, they are poisonous to higher organisms; at lower concentrations it is an essential trace nutrient to all higher plant and animal life. The main areas where copper is found in animals are tissues, liver, muscle and bone.

Copper ore processing plant

(1) disseminated copper ore flotation

Generally use not at all hard processes, through a grinding fineness -200 fine mesh} about 50% to 70%, 1 roughing, 2 or 3 times selected, 1 or 2 times sweep the actual election. Comparison of disseminated copper minerals, such as small size, may consider the stage of grinding and separation processes. Treatment spot copper concentrator, mostly coarse concentrate regrinding – an array of stage grinding and separation processes, and its essence is mixed – flotation process. First through a coarse grinding, roughing, scavenging jaw crusher and then difficult concentrate regrinding be selected high-grade copper mineral concentrate and concentrate. Coarse Ground degrees -200 mesh about 45% to 50% after which pulverized degree of -200 mesh regarding 90% to 95%.

(2) Thick compact copper ore copper ore flotation equipment chalcopyrite and pyrite as tight symbiosis, pyrite is often of secondary copper-activated pyrite content material is high, difficult to inhibit the separation hard. Sorting process required by copper concentrate and concentrate simultaneously. Usually after the election of copper mineral tailings is pyrite concentrate. If the ore gangue content in excess of 20% to 25%, sulfur concentrate needed to get re-sorting ball mill. Dense copper ore processing, often using two stages of grinding or grinding, grinding fineness requirements smaller. Also larger amount of reagent, xanthenes dosage 100g / ({t|capital t|big t} ore) above, lime 8 ~ 10kg (t ore) above.

Copper ore process

Most copper ores contain only half the normal commission of copper metal bound up inside of valuable ore minerals, with the remainder of the ore becoming unwanted rock or gangue minerals, typically silicate minerals or oxide minerals that there is often no value. The average grade of copper ores within the 21st century is below 0. 6% Cu, with a proportion of ore minerals being lower than 2% of the total volume from the ore rock. A key objective in the metallurgical treatment of any ore may be the separation of ore minerals from gangue minerals inside the rock. The first stage of any process inside a metallurgical treatment circuit is combination, where the rock particles are reduced in dimensions such that ore particles can end up being efficiently separated from gangue particles, thereafter followed by a process of physical liberation from the ore minerals from the rock. The process of liberation of copper ores is determined by whether they are oxide or sulfide ores. For oxide ores, a hydrometallurgical liberation process is usually undertaken, which uses the soluble nature of the ore minerals to the benefit of the metallurgical treatment plant. For sulfide ores, both secondary (supergene) as well as primary (unweathered), froth flotation is utilized to actually separate ore from gangue. For special native copper bearing ore bodies or parts of ore bodies rich in supergene indigenous copper, this mineral can be recovered with a simple gravity circuit.
