The ore is conveyed via covered, heated conveyors to the Mill Building. At the Mill Building, the size of the ore is further reduced in semi-autogenous (SAG) mills, rod mills and ball mills. All milling is done wet . A copper-nickel concentrate is extracted from the slurry via a series of magnetic separation, flotation and thickening steps.

Application: Energy saving mining ball mill is a key equipment in beneficiation plant.It is widely used in ore dressing production line such as Gold ore, Cooper ore, Magnetite ore, Antimony, Calcite, Kaolin, Mica, Clay, Bentonite etc Ferrou metal or Nonferrous metal materials.
The ore is ground into a fine powder by large rotating mills. The two types used in the Mission South Mill are called SAG (semi-autogenous grinding) mills and ball mills. SAG mills use larger pieces of ore to break up the smaller pieces (autogenous — does it by itself). The larger pieces break down as well.
The run-of-mine is processed by means of standard primary crushing and conveying, SAG milling (a semi-autogenous mill that uses a large rotating drum filled with ore, water and steel grinding balls to transform the ore into a fine slurry), ball milling, copper concentrate flotation, tailings disposal, concentrate thickening, filtration and load ...

The copper–lead–zinc ores have an origin similar to copper–zinc and lead–zinc ores, the exception being those ores that contain copper, lead and zinc as the principal economic minerals. In addition, some of these ores contain significant amounts of precious metals and, more rarely, cobalt and nickel.
Copper Mining Info The above flowsheet shows a basic copper mine process, from mine to metal. There are two distinct types of copper ore, the sulfide ore and the oxide ore. The sulfide ores are beneficiated in flotation cells, while the oxide ores are generally leached. First the copper ore from a open pit mine is blasted, loaded and ...
Copper Ore Types: Sulfides vs. Oxides. ... Read on for an overview of the types of copper oxide ores and copper sulfide ores, with a focus on how they're processed. For investors interested in ...
May 06, 2016· Radomiro Tomic is primarily a heap leaching operation which processes oxide copper material. As a cost saving measure, Radomiro Tomic does not have its own sulphide processing plant but instead conveys sulphides to Chuquicamata. The mill employs two 32-ft SAG mills feeding a complex arrangement of rod and ball mills.
Ore is broken down into smaller pieces. The large pieces of ore are collected by haul trucks and taken to a mill, a large rotating device which makes the pieces smaller through crushing and grinding. There are two types of copper ore (sulphide ore and oxide ore), and each is treated differently in order to liberate the copper inside. Step 3

The inside of the mill is lined with lifting plates to lift the material inside the mill, where it then falls off the plates onto the rest of the ore charge. SAG mills are primarily used at gold, copper and platinum mines with applications also in the lead, zinc, silver, alumina and nickel industries. Pebble mill

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, due to the different ...
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.
RECOVERY OF COPPER FROM OXIDE COPPER ORE BY FLOTATION AND LEACHING Kiraz, Emirhan M.S., Department of Mining Engineering Supervisor: Prof. Dr. Mustafa Ümit Atalay December 2014, 65 pages The aim of this study was the recovery of copper from the oxide copper ore by froth flotation and agitating sulphuric acid (H 2 SO 4) leaching.

Oct 15, 2019· The leaching process involves the extraction of copper from solid copper oxide using the sulphuric acid solution. Although the acid concentration in the SAG mill circuit is lower than that in the leach tanks, it is very effective because of the high kinetic energy in the SAG mill.
17.8 Flotation of Oxide Copper–Gold Ores. Oxide copper– gold ores are usually accompanied by iron hydroxide slimes and various clay minerals. There are several deposits of this ore type around the world, some of which are located in Australia (Red Dome), Brazil (Igarape Bahia) and the Soviet Union (Kalima).
The project comprises of an open-pit mine and an on-site concentrator to produce copper cathode from oxide ore and copper concentrate from the sulphide ore. Molybdenum is also being produced as a by-product. Approval for the copper project was issued by the board of Kazakhmys in December 2012 and construction works began in 2013.
The mill charge volume has a great impact on grinding efficiency. For efficient grinding, autogenous (AG) and semi-autogenous (SAG) mills need to be operated with the correct charge in order to maximize their throughput while avoiding overloading. The Outotec MillSense sensor system gives a precise indication of the mill charge volume.
Oct 12, 2017· In ancient time, the mills were operated with muscle power (by hands), water animals and wind. They were totally based on the mechanical energy by natural resources and living beings.There are many types of mills which are used in the grinding industries. Today we will discuss about two important mill, sag mill and ball mill.
