Metal Roasting & Metal Refining Services
The slag will scavenge the impurities and leave behind pure metallic slurry that is then sampled and poured into bars During this process, potential losses can occur due to the migration of precious metals into the slag or if the furnace temperature is too high, blowing the precious metals up the flue...

Lead Recycling
The mine and metal production, and the metal use of the last five years, are given in Table 81It is notable that in spite of the gradually more stringent ban of lead from a number of its traditional applications (such as pigment, antiknocking agent, solder alloy, plumbing, gun shot), the level of lead usage has doubled in the last 30 years ()...

Copper Scrap
Carbothermic slag reduction is done to enhance the separation of metals and subsequently metal recovery Production of high-grade mattes results in a highly oxidized slag containing considerable amounts of copper oxides, which requires reduction of the slag to reduce copper and other metals into other phases, eg matte, speiss and gas phase...

Recycling of Metals
recycling of iron scrap For reasons of flexibility (high temperatures possible, mode of electrical operation, electrode positioning, etc) the electric arc furnace is increasingly used for non-ferrous recycling purposes, few of which are listed below: l recycling of NiMH and Li/Co-batteries l recovery of precious metals from spent catalysts...

The Process
Meanwhile, the non-precious metal contaminants are carried off into the slag The crucible is removed from the furnace and poured into a mold When cool, the slag is discarded and the lead "button" cleaned of any residual slag This entire process, therefore, selectively collects all the precious metals from the sample and alloys them with lead...
