by products of iron extraction. Iron Extraction by Blast Furnace Metallurgy - Procedure. The purest form of iron commercially available is the Wrought Iron. It is made by heating cast iron in a furnace lined with Haematite (Fe2O3). Carbon is reacted with Haematite to produce pure iron and carbon monoxide gas which escapes. Fe2O3 +3C = 2Fe + 3 CO.
The basic principle is that activated carbon can adsorb liquid gold in alkaline cyanide solution. With the desorption of gold-bearing carbon and the regeneration of degold-bearing carbon gradually mature, activated carbon can be recycled. CIL process has become the main method of gold extraction and has been rapidly promoted, giving full play ...
Carbon-in-Pulp (CIP) and Carbon-in-Leach (CIL) processes have surface areas of about 1000 m²/g i.e. one gram of activated carbon (the amount of which will occupy the same space as the end of a person's thumb) has the same surface area as two football fields. The high surface area is contained in the millions of pores of varying sizes, these being

A process for adsorbing gold from a leach pulp by means of activated carbon is described in which the leach pulp (the leach solution together with the subdivided gold bearing ore) is diluted to a specific gravity of less than that of the activated carbon and is subsequently passed upwardly through a multistage liquid/solid contacting column.
carbon are mechanically mixed with the pulp in an adsorption tank, and gold-loaded carbon granules are separated from gold-depleted pulps by screening. The screening operation is done at screen mesh sizes that are intermediate between the smallest carbon granules and the largest particles of the pulp. The basic difference between CIL and CIP is ...
