Pyrometallurgy involves the treatment of ores at high temperature to convert ore minerals to raw metals, or intermediate compounds for further refining. Roasting, smelting and converting are the most common pyrometallurgical processes. A roasting process is used to extract metals from sulfide ores: in this process the ore is heated in the presence of oxygen and the sulfur is oxidised and driven off as sulfur dioxide. Some metals in this process remain in the sulfide form, while other metals are turned into an ...

Working solvent from the washing chamber passes through several filtration steps before it is returned to washing chamber. The first step is a button trap which prevents small objects (lint, fasteners, buttons, coins etc) from entering the solvent pump. Next the solvent passes through a filter unit which removes lint and insoluble suspended soils from the solvent. Several different types are used, most filters use an ultra fine mesh to support a thin layer of filter powder (made from diatomaceous earth and activated clays). Some machines use powderless filters which are capable of removing soil part ...

There are three ways to convert N2 into a more chemically-reactive form: Biological fixation: some bacteria (associated with certain plants, leguminosae) and certain blue-green algae (also known as cyanobacteria) are able to fix nitrogen and assimilate it as organic nitrogen. Technical N-fixation: in the Haber-Bosch process N2 is converted to-gether with hydrogen gas (H2) into ammonia (NH3). Combustion of gasoline and fossil fuel (automobile engines and thermal power ...
