The effects of declining ore grades on embodied energy and greenhouse gas emissions from the direct smelting of copper ore are shown in Table 3, Table 4 and Fig. 8. Table 3. Effect of ore grade on embodied energy (MJ/kg) .
The cyclone converter furnace (CCF), developed initially by Hoogovens Staal BV, has been considered for use in combination with the bath smelting reactors described previously. 23 In the CCF, ironore fines are introduced at the top of the furnace and hot offgasses from the smelter reactor enter from the bottom. The feed gas heats and .
Equipment Used For Firing/Smelting Ore. Furnace Or Oven For Firing/Smelting: It must heat to 1950 degrees F for gold and 2100 degrees F for silver. A muffle furnace is best. It fires to about 2300 degrees F and the ingredients can be easily added to the ore while firing. Crucible: Clay or graphite crucible to use in a muffle furnace. Other types of crucible can be used in an .
The off gas from the furnace is a very large energy loss. By measuring the gas flow, the enthalpy is determined, and the plant can then work on reduction and optimization of the hot gas in order to decrease plant energy consumption.

What is "smelting"? Put simply smelting is a way of separating base metals from rock (called ore) by using high heat (kilns and or furnaces) along with chemicals or gasses. The smelters in Durango separated metal from ore producing silver, gold, copper, lead, iron and other metals.
The sulphur dioxide gas produced in the furnace is extracted by centrifugal fans and discharged through ducting to the acid plant, an essential part of every copper smelter. Here it is processed and converted to sulphuric acid being used in smelting and ore processes, any remaining acid being sold off as a by product.
In the smelting process, borax helps to reduce the gold smelting point of the charge and capture metallic oxides. The addition of this reagent must be controlled; otherwise the slag will be extremely hard and nonhomogeneous.
