CiteSeerX Document Details (Isaac Councill, Lee Giles, Pradeep Teregowda): Abstract – By placing additional demands on energy and gas flow, the moisture content of a copper concentrate has an adverse effect on the smelting process. Different drying technologies, such as directly heated rotary dryers, flash dryers, and steam dryers, are available to solve this problem.
Limitations and cost of filtration generate a feed product which causes clogging and build up. The solution is back mixing, which is far more costly in a rotary dryer configuration situation that that of a flash dryer, but still yields an inconsistent variable final product.

The copper concentrate capacity was only 8 tph corresponding to about 12 320 tpa blister copper. The original dimensions of the reaction shaft were h= m * I = m. During the first years
identical flash dryers can be fed from six silos. From the flash dryers concentrate is transported pneumatically to a 3 000ton dry concentrate storage silo. The flash dryers are rated at a nominal 66 tph of dry concentrate at 14% moisture, while the furnace can smelt 90 tph of dry concentrate. Therefore both flash dryers are required to operate
dryers of low capacity most often operating in batch mode. In this paper, it is therefore desired to model and simulate the drying behavior of an industrial copper concentrate rotatingcoil dryer using the penetration model of [1]. 2. Model Description . The penetration model of Schlünder and Mollekopf [1] was developed for indirect drying
Copper Concentrate Dryer In Mongolia Solustrid Heavy. Study results and than 4000 tons per day of wet copper concentrate feed to the smelter is dried in a large rotary kiln The dryer is heated by natural gas and consumes more than 800000 MMBtuyr or 30 of the smelters total fuel consumption.
Kumera Steam Dryer for Nickel Concentrate NOx and dust Drying is necessary in many smelting technologies for example all flash smelting processes of copper and nickel production Kumera Steam Dryer is widely used all over the world due to its lowest opex compared to any other concentrates drying .

Moisture in wet concentrate has a negative effect on the performance of the smelting furnaces when it is fed directly to the furnaces, namely increasing the energy consumption and the offgas flow. There are several drying technologies available for drying copper concentrate, varying from direct heated rotary dryers and flash dryers to indirect ...
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 .
The production of copper in the flash smelting process is accompanied with a large amount of copperrich slag, which has to be treated with the aim of copper recovery. Copper flash smelting consists of blowing fine, dried copper sulphide concentrate and silica flux with air, oxygenenriched air or oxygen blast into a hot (≈1500K) hearthtype ...
