ALT (SGPT) Test. This blood test measures an enzyme called alanine transaminase (ALT). Enzymes are chemicals that help the cells of your body work. ALT is an enzyme made in the liver. It is released into the blood when tissues are damaged. This enzyme is also called serum glutamic-pyruvic transaminase, or SGPT.
Iron and steel slags are coproducts of iron and steel manufacturing. In the production of iron, the blast furnace is charged with iron ore, fluxing agents, usually limestone and dolomite, and coke as fuel and the reducing agent. The iron ore is a mixture of iron oxides, silica, and alumina.
The metal ore, a mineral or mixture of minerals from which economically viable amounts of metal can be extracted, i.e. its got to have enough of the metal, or one of its compounds, in it to be worth digging out! Ores are often oxides, carbonates or sulphides.s described above, the carbon removes the oxygen from the metal oxide. Iron ore is used to make iron and steel and iron is produced in a blast furnace by reducing iron oxides with carbon and it is the carbon that removes the oxygen from the iron oxides the carbon is known as the reducing agent.
