The Process Of Refining Metal

Refining (metallurgy) - Wikipedia

The product of the blast furnace is pig iron, which contains 4–5% carbon and usually some silicon. To produce a forgeable product a further process was needed, usually described as fining, rather than refining. From the 16th century, this was undertaken in a finery forge. At the end of the 18th century, this began to be replaced by puddling (in a puddling furnace), which was in turn gradually superseded by the production of mild steel by the Bessemer process.

15-05-2020· The metal obtained by any of the above methods is usually impure and is known as crude metal. Therefore, the crude metal is to be purified. The impurities may be in the form of. 1) unreduced oxides of the metals. 2) non-metals like C, Si, P, As, S etc. 3) foreign metals. 4) slag or flux. The process of purifying the crude metal is called refining.

Topical Bible: Refining

The ancient process of refining gold has already been described under METALLURGY (which see). Most of the Bible references are to the refining of silver ( Proverbs 25:4 Zechariah 13:9 Isaiah 48:10 ). The silver used by the ancients was probably obtained by smelting lead sulfide ore, rich in silver (argentiferous galena).

Refining - Wikipedia

Refining (also perhaps called by the mathematical term affining) is the process of purification of a (1) substance or a (2) form.The term is usually used of a natural resource that is almost in a usable form, but which is more useful in its pure form. For instance, most types of natural petroleum will burn straight from the ground, but it will burn poorly and quickly clog an engine with ...

Metallurgic Processes | Boundless Chemistry

Electro-refining is used to dissolve an impure metallic anode (typically from a smelting process) and produce a high purity cathode. Fused salt electrolysis is another electrometallurgical process whereby the valuable metal is dissolved into a molten salt, which acts as the electrolyte, and the valuable metal collects on the cathode of the cell.
