Chapter 6 Copper Production Technology

mans found nearly 100 lens-shaped ore bodies in the Rio Tinto copper district. Modern geologists have found only a few additional deposits, and almost all of Rio Tinto’s modern production has been from ore first discovered by the Remans.3 At Rio Tinto, the Remans mined the upper, ox-idized, part of the ore and collected the copper-

Environmental Guidelines for Copper Smelting

The smelting process typically produces less than three tons of solid waste per ton of copper produced. Pollution Prevention and Control Process gas streams containing SO2 are processed to produce sulfuric acid, liquid sulfur dioxide, or sulfur. The smelting furnace will generate process gas streams with SO2 concentrations ranging 0.5-80% percent

Benefits of Agglomeration in an SX EW Process for Copper

Heap Leaching Copper Ore with Agglomeration. Crushed copper ore is first typically processed via heap leaching. An effective leaching step is critical to SX-EW, as it sets the stage for how much copper can be recovered. For this reason, the heap leaching step is commonly preceded by agglomeration of the ore in a rotary drum agglomerator.

Estimated Water Requirements for the Conventional

the amount of water required to process copper sulfide ore through a conventional crush-grind-flotation-concentrate circuit ranges from roughly 1.5 metric tons (t) to about 3.5 t of water to process 1 t of ore [Wels and Robertson, 2003, 2004; Misra and others, 2005; Wills and Napier-Munn, 2006; Chilean

Reasons for Copper Ore Sorting cont. • Pre-concentrate feed into high-grade and low-grade stockpiles: – Optimize multiple process streams i.e. send ore to either mill, heap leach or smelter. – Allows smaller mills to be built or increase capacity of an existing mill. – Manage ore blending programs more effectively.

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..

What Is Copper Smelting with pictures

Kirsten C. Tynan Copper wire. Copper smelting is the process of separating copper metal from the rock in which it is naturally embedded by melting it. This is accomplished through a series of several processing steps. The term copper smelting may refer to this melting step in particular or it may refer somewhat less formally to the entire process overall.
