Copper processing - Roasting, Smelting, Converting: Once a concentrate has been produced containing copper and other metals of value (such as gold and silver), the next step is to remove impurity elements. In older processes the concentrate, containing between 5 and 10 percent water, is first roasted in a cylindrical, refractory-lined furnace of …
Common geometries for hoppers, bins, and silos include (a) conical, (b) wedge, (c) transition, and (d) pyramidal. In bulk solid storage discussions, the terms hopper, bin, and silo are often used interchangeably. Hopper and bin frequently refer to small storage vessels, while silo usually refers to tall vessels that store several tons of material.

The use of shop-welded steel hopper tanks is common in dry bulk storage applications. Typically, the average size shop-welded tank used to store bulk materials will range from 3500 to 7000 cubic feet per unit. In select applications, shop-welded hopper tanks can exceed capacities of 10,000 cu ft of storage.
The Basics of Copper Mining and Processing. Mined from open pits, copper ore must be crushed as part of the process that occurs between extraction and production. Using today's compact mining equipment, copper ore is extracted from the mine. After the ore is crushed, it's roasted, which helps to convert sulfides to oxides.

Telfer is a gold/copper operation located in the Pilbara region of Western Australia. Open pit mining (Main Dome) recommenced in 2003, followed by an underground mine (Telfer Deeps) in mid-2006. Copper deportment in the ore varies signi cantly from mainly chalcocite in the open pit fi ore to predominately chalcopyrite in the underground ore. In
General Information/Equipment Design. Self-dumping hoppers are designed so they can be easily moved manually or by forklift. They are used for transportation as well as storage. For space conservation, self-dumping hoppers are stackable. The hopper pictured below would typically be loaded by a conveyor.

1. Copper Flotation. As a commonly used process for copper ore beneficiation, flotation can be used for the separation of copper sulfide and oxidized copper ores. The main process of copper ore flotation is rough as follows: ore crushing and screening → stage grinding stage flotation → concentration and dehydration → copper concentrate.

Types of Hoppers. There are many different types of hoppers, dumpers, and tippers. Examples include: bottom hoppers, live hoppers, cropper hoppers, cullet hoppers, and sludge hoppers; dump boxes, chip boxes, trash boxes, and scrap boxes; and various types of refuse equipment. Bottom hoppers are designed so that stored materials can be …

The conditioning tank allows for a homogeneous blend to be fed to the flotation circuit at a constant rate, allowing for optimal process control. A properly controlled condition tank reduces operating costs, increases process performance, and improves circuit control. Choosing a suitable agitator is key to successful conditioning tank operation.
A numerical model to evaluate the relative wear on mining hoppers is proposed. • The model is based in the Discrete Element Method to simulate the flow of rocks. • Archard's model is used to compute the wear at the bottom of the hopper. • Rocks are modeled as clusters of spheres to mimic its shape without increasing the …
Copper ore processing. According to the metallurgy process, the copper ore is divided into three natural types by the ratio of copper oxide and copper sulfide. That is, sulfide ore, containing less than 10% copper oxide; oxidized ore, containing more than 30% copper oxide; mixed ore, containing 10% to 30% of copper oxide.
Agitation leaching in stirred tanks is applied to both oxide and sulfide materials: the PLS concentrations can be up to 25 g/L Cu. Most copper minerals are amenable to leaching under atmospheric ...
A Copper Flotation Flowsheet. 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. In general most operations of this type have two or more …
