Chemically, concentrates smelted in flash furnaces contain 2030 mass % Cu, 2535% Fe and 2535% S. The process takes place in a flash smelting furnace, which schematically is presented in Figure 1. Main feedstock of the process is a dry CuFeS concentrate. Very roughly speaking, dry concentrate is blasted with O 2 in the reaction shaft. The ...
The old established method of flash drying has only recently been applied to the minerals industry. Adapting their own system, Drytech has achieved highly flexible, effective concentrate processing and drying from feed with a high 26% moisture down to bone dry.

ISASMELT technology has been applied to lead, copper, and nickel smelting, and by 2013 fifteen plants were in operation in ten countries, with another five in various stages of development. The installed capacity of the operating plants in 2013 was over 8 million tonnes per year (t/y) of feed materials, with additional capacity to come on line in 2013 and 2014.

The Inco flash furnace has endwall concentrate injection burners and a central waste gas offtake, while the Outokumpu flash furnace has a watercooled reaction shaft at one end of the vessel and a waste gas offtake at the other end. While the INCO flash furnace at Sudbury was the first commercial use of oxygen flash smelting, fewer smelters ...
concentrate dryer flash smelt identical flash dryers can be fed from six silos. From the flash dryers concentrate is transported pneumatically to a 3 ton 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.

The concentrate and flux are blended in controlled amounts and fed into a 185 stph gas fired rotary dryer. The wet charge enters the dryer at 8% moisture and is dried to .2% moisture. The dried charge is pneumatically conveyed to a 640 ton dry charge bin located above the flash furnace.
Chapter 7 Energy Use in the Copper Industry All aspects of copper production require energy, whether i n the form of electricity, explosives, or hydrocarbon fuels (diesel, gasoline, natural gas,
This paper presents mass balance calculations using genetic algorithms for copper smelting in an Outokumpu flash furnace. Based on the elemental composition of the copper concentrates being fed to the reactor, the mineralogical composition of the concentrate .
Flash furnace smelting combines the operations of roasting and smelting to produce a highgrade copper matte from concentrates and flux. In flash smelting, dried ore concentrates and finely ground fluxes are injected together with oxygen and preheated air (or a mixture of both), into a furnace maintained at approximately 1000°C (1830°F).
Answer: First, Stop using your dryer until this problem is resolved. This is a fire hazard and could cause a fire. Your issue is more than likely a lint build up lint that comes off of your clothes as you dry them becomes trapped in the dryer itself and in the venting duct that connects from the back of the dryer to the wall.

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
