Smelting is a process of applying heat to ore in order to extract a base metal. It is a form of extractive metallurgy.It is used to extract many metals from their ores, including silver, iron, copper, and other base metals.Smelting uses heat and a chemical reducing agent to decompose the ore, driving off other elements as gases or slag and leaving the metal base behind.
The extraction process uses hexane or other solvents to wash the soybean oil from the prepared soybean flakes. The design of the equipment varies so that Crown can optimize the amount of solvent and bed depth needed to efficiently wash the flakes, the contact time of the solvent and flakes, and the power and utilities needed to run the equipment.
12%In the production of copper from sulfide ore, slag accumulates at the processing plant. In the present work, the phase transformations that occur in such slag during its reduction by the gasification products of carbon at 1100 and 1200°C are investigated. Experiments show that most of the iron present in such slag may be converted to metallic form by the gasification …

The objective was to extract sufficient cobalt from the leach liquor so that the resultant nickel raffinate met the cobalt requirements for LME Grade Nickel, (Ni:Co ratio > 666:1). In effect this meant >98.6 % cobalt extraction was required, depending on the extent of nickel extraction.
Nevertheless, iron in plant extracts was found to be independent of the illumination conditions where the sample was maintained during the extraction. Ferric iron added to a plant extract was completely reduced in the darkness. These data seem to indicate that if extraction of ferric iron occurred, it would be reduced and measured as ferrous iron.
