Several laboratory and pilot scale plants are operating, and a plant study by a South African manufacturer for metal recovery from slag at an operating ferrochrome plant included a jig plant to treat the finest cut of the slag feed of a 2mm top size. The results indicate commercial viability of the Yang jig column.

The ferrochrome is tapped into sand moulds where it is left for a few hours to cool down and then removed to the breaking floor. The finished product is crushed and screened to exact customer requirements. After the slag is cooled down, it is removed to a slag dump from where it is fed into the alloy recovery plant.
Ferrochrome smelting slag is a waste smelting slag of ferrochrome smelting process, in which there is a certain amount of ferrochrome in the slag, if not reuse the resource, it causes waste of resources and pollution to the environment.

MARS (Metal Alloy Recovery Systems), Ferrochrome from slag recovery plant at Middelburg Ferrochrome. 2. OPERATION OF THE APIC CLASSIFIER The Apic classifier is similar to an elutriator, but its operation (separation on basis of size) differs significantly. An elutriator is used as a device for very sharp size cuts. These are achieved by using high
For instance, where Cr(VI) was detected it more likely occurs from the slag than from the metal and could arise either from the partially altered chromite or baghouse dust found on the dump. The removal of Cr(VI) from a synthetic solution containing 40 mgl −1 Cr(VI) was investigated.
The recovery of ferrochrome from slag at Zimasco, The recovery of ferrochrome from slag at Zimasco, It is estimated that in Southern Africa alone there are some 60 million tons of Ferroalloy Slag containing entrained metal valued at about 1 billion A highly efficient process has been developed to recover the valuable metals from slag in a form that is as far as possible directly salable Six commercial plants .
Heterogeneity in ferrochrome slag has been found to depend significantly on the amount of alloy entrainment in slag, and therefore the slag viscosity, tapping temperature and chemical composition. One can therefore conclude that the sampling constant and therefore sample mass is dependent onfurnace operating conditions. IV

The ferrochrome plant will be brutal for the roads in and around the city. There will be 234 incoming trucks every day carrying heavy loads of ore from the Ring of Fire. Outgoing there will be 167 trucks per day carrying slag, waste and ferrochrome (much to Pittsburgh).
important during steps such as ferrochrome recovery from slag and enduses of crushed slag. When metal recovery from slag is part of the production process, contaminated water is also produced and may require treatment. Some ferrochrome facilities sell crushed slag for industrial enduses, a potential recognized by Cliffs. There are environmental concerns about contaminant leaching that must be .
"We invested in a recovery plant and managed to salvage between 500700 tonnes of ferrochrome per month, thereby adding value to our operations." Further, in a move to enhance the energy efficiency of plant operations, Gulf Mining Group has set up a briquetting plant in Samayil, the output of which will be used in the Suhar smelter.
Copper slag is a byproduct obtained during smelting and refining of copper. The waste copper slag can be used as abrasive tools, road construction, and ballast. Despite increasing rate of reusing copper slag, the huge amount of its annual production is disposed in dumps or stockpiles to date.
The CHROMIC project (effiCient mineral processing and Hydrometallurgical RecOvery of byproduct Metals from lowgrade metal contaIning seCondary raw materials) aims to recover chromium from steelmaking and ferrochrome slags to regain valuable resources and simultaneously reduce potential environmental impacts.
