The rotary drying system consists of a final concentrate thickener to dewater the slurry to about 6070 solids a vacuum filter disc or drum with the necessary vacuum pumps to dewater the thickened material further to about 1420 moisture on a dry basis a collecting belt underneath the filter to receive the filter cake a stainless steel type ribbon screw conveyor extending into the
Dried copper concentrate is introduced to a smelterconverter that utilizes oxygen enrichment in the smelterconvert process. The copper concentrate was previously dried in a gas suspension or fluid bed dryer by contact with nitrogen gas that was a byproduct from the oxygen plants utilized to support the smelter.

Perhaps the most widely used chemical to clean copper is acetic acid. Many people may not know it, but this chemical is commonly found in homes, but called by another name vinegar. Vinegar is actually acetic acid. This acid is quite weak, but it does a good job in cleaning the stains, tarnishes and oxidized residue on copper surfaces.
Copper concentrate is the first commercial product of the copper production line and is composed of approximately equal parts of copper, iron and sulfide. Concentrates are the raw material for all copper smelters, which by processing it obtain an impure form of metallic copper, anode or blister copper, which is later used to produce high purity
the rotary drying machine is mostly used for drying minerals concentrate ore in the final process. This dryer is high effect and energy saving, the power of mineral drying equipment can be natural
Copper concentrate drying method rotary kiln drying and air drying. Metal sulphide concentrate drying characteristics and selection of. However, spin flash dryer generally use hightemperature gas as drying medium change in particle size distribution of copper concentrate. Copper concentrate drying curve
Abstract The Schlnder and Mollekopf 1 penetration model was used to simulate the drying of copper concentrate in a continuous indirect rotatingcoil dryer located at a Chilean industrial copper smelter. The dryer consists of a 8.48 m long pan with a cylindrical bottom corresponding to an inner diameter of 2.77 m and a maximum depth of 1.66 m.
Carefully Choosing Coil Cleaners Proper selection of chemicals and cleaning techniques are critical in AC coil cleaning. A pplying improper cleaning solutions and techniques for airconditioning condenser and evaporator coils can not only damage the coils, but it can also cause longterm premature refrigerant leaks and heattransfer reductions.
Kumera Steam Dryer for Copper Concentrate Kumera Steam Dryer is a patented solution for drying copper concentrate as well as other abrasive materials. Steam is normally available from a wasteheat boiler, serving Kumera Steam Dryer, but it can also be obtained from a recovery boiler of the acid plant at the smelter.
Handling guide for copper concentrate in bulk Although copper occurs naturally in a pure state, its primarily mined from the minerals chalcopyrite, bornite, and malachite. Copper ore is extracted form the earth, then converted into copper concentrate, which is then roasted, smelted and converted into refined copper.
