Copper is used for electronics, construction, and metal alloys. Moly is mostly used to make metal alloys, and as a catalyst. As markets need copper and moly, their ores are separated, concentrated, and sold separately. This separation and concentration of copper and moly is called the "copper-moly flotation circuit." Flotation – Sulfides


Most flotation circuits include an initial stage of rougher flotation, followed by a scavenger stage of flotation. The objective of passing through the rougher and scavenger flotation circuits is to maximise recovery of the desired minerals into relatively low grade concentrates that may typically contain 5-15 weight percent of the ore feed ...


copper ore primary mill circuits types. Copper Flotation Mineral Processing & Metallurgy. Mar 19, 2017· Because the copper in this type of ore usually assays only plus or minus 1% copper, the porphyry copper operations must be relatively large in order to be commercial. The flowsheet in this study illustrates a typical 3,000 ton per day operation.


Sep 04, 2020· copper ore primary mill circuits types . Copper ores Danafloat. The largest source of copper is from porphyry ore deposits in which one or a combination of the aforementioned minerals occurs. A typical copper sulphide ore contains various levels of iron sulphide types that generally include pyrite (FeS2) ...


Copper Ore Primary Mill Circuits Types. ... Figure 1 Proposed HPGR Flowsheet for Clayish Ore In this circuit the primary crushed ore is slurried in a low power autogenous mill where weaknesses in the fresh rock are immediately exploited and hard material is scrubbed The autogenous mill is an unconventional design in that it.


Copper Ore Primary mill circuits types Stone Crusher In a typical copper concentration plant for example crushed ore is fed into a SAGBall mill circuit with contact us. Ball Mill. Feeding size: ≤25mm . Processing capacity: 0.65-615t/h .


For example, assume that raw ore is a two component system comprised of a valued mineral and host rock having relative densities of 6.30 and 2.65, respectively. The amount of valued mineral is 30% of the total ore.Total Solid Mass, M: Mineral + Host Rock – 30 + 70 = 100 Total Volume, Vs: Total Solid Relative Density


Copper processing is a complicated process that begins with mining of the ore (less than 1% copper) and ends with sheets of 99.99% pure copper called cathodes, which will ultimately be made into products for everyday use.The most common types of ore, copper oxide and copper sulfide, undergo two different processes, hydrometallurgy and pyrometallurgy, respectively, …

Copper extraction - Wikipedia

Copper extraction refers to the methods used to obtain copper from its ores.The conversion of copper consists of a series of physical and electrochemical processes. Methods have evolved and vary with country depending on the ore source, local environmental regulations, and other factors.. As in all mining operations, the ore must usually be beneficiated (concentrated).


Copper ores. An ore is a rock containing enough valuable mineral to make it worth extracting. In the case of copper, it is worth extracting when there is about 2 kg of copper per 1,000 kg of ore (0.2%). Copper minerals are found in over one hundred varieties, although only a few have been worked for copper on a large scale.

The current copper concentrator is a standard semi-autogenous, ball mill and flotation circuit. While the block cave is being established, a second process plant will be built using vertical roller mills for comminution and copper flotation, producing a concentrate that will then be transported to port and subsequently to smelters by ships.


Copper Ore Primary Mill Circuits Types. Open Pit6 and the alternative milling circuits proposed have been simulated with both ore types in mind It indicates that MMZ ore may be significantly variable The comminution survey has clearly shown that the effect of steel in the mill and ball size greatly influences the progressive grinding of critical size material and that the


The grinding circuit consists of two lines with one Autogenous mill (AG) and one pebble mill (PM) each. The primary objective of the grinding circuit is to grind as much material within a certain particle size distribution. According to Bond's equation, the more energy is put into the system, the finer the product one obtains.

Several gravity options were reviewed for the secondary (ball mill), tertiary and regrind grinding circuits. Due to the coarse nature of the native copper and the feed size to the gravity circuit required in the ball mill circuit (up to 10mm), there were only 2 gravity options reviewed for this circuit. The first was Dense Media


The primary reason for the significant comminution circuits is because in gold mining the grades are notably low and thus excessive waste material is present, resulting in high mill feed rates. If the ore rock is highly fractured and/or brittle, it is likely that an AG mill be the most economical option in lieu of a SAG mill.
