applied to other separation processes. However, in most alternative separation processes, e.g. absorption, adsorption, and extraction, the two phase system is created by the addition of an external substance (entrainer or solvent) that has to be removed later on in an additional separation process. In distillation however, the two phase

Flotation is widely used to concentrate copper, lead, and zinc minerals, which commonly accompany one another in their ores. Many complex ore mixtures formerly of little value have become major sources of certain metals by means of the flotation process. This article was most recently revised and updated by Chelsey Parrott-Sheffer, Research Editor.

Lead smelting rotary furnace is widely used for the lead paste smelting of battery recycling plants all over the world. The lead paste, lead grid or lead ore will have reduction reaction and become crude lead. The crude lead can be sold directly or put into lead refining kettle/pot for further refining process and being casted into ingots.

Abstract: A process for the upgrading of raw hydrocarbon streams rich in heteroatomic polar compounds and/or unsaturated moieties involving the extractive oxidation of sulfur, nitrogen, conjugated dienes and other unsaturated compounds from said streams, the said process comprising treating said streams with a peroxide solution/organic acid couple and an iron oxide catalyst which is a limonite ...

The technology used is presumed to have included roasting of the ore, smelting in a furnace, separation smelting (segregation and liquation), and cupellation. In the second half of the 20th century, lead has been produced primarily from complex ores by flotation concentration, agglomerative roasting, reduction smelting in shaft furnaces, and ...
