About Atoll Metal Recovery Dr. Peter Scotturanium
Atoll still operates the plants in Sweden Romania Turkey and the USA as well as one plant in RSA. The other plants have been sold to the slag owners. Although metal from slag recovery remains a key focus Atoll is turning more of its attention to the beneficiation of minerals by jigging particularly manganese and iron ores and coal.
Chromite - ScienceDirect
Ferrochrome is made by smelting chromite ore in an electric arc furnace with flux materials quartz dolomite limestone and aluminosili es and a carbonaceous reductant wood chips coke or charcoal Kleynhans et al. 2012 USEPA . The solid products obtained from smelting ferrochrome are metal slag and dust.
PRODUCTION CHARACTERISTICS AND USE OF FERROCHROMIUM SLAGS
the right slag composition. The slag composition is tested every day by sampling and analysis. The typical ferrochrome slag composition is 30 % SiO 2 26 % Al 2O3 23 % MgO and 2 % CaO. The chrome content in the slag is about 8 % and the iron content 4 % respectively. Ferrochrome slag is acid. Its basicity is 0.8 when it is calculated by

Samancor Products - Samancor Chrome
To improve total ferrochrome recovery while maintaining a high-quality product alloy recovery plants are utilised to recover the ferrochrome from the slag produced during the charge chrome process. The slag which has a metallic content of approximately 4 percent is processed through a series of crushers and broken down to minus 15mm material.
Alliance - Metal Partner GmbH
Ferrochrome Beneficiation. Ferrochrome Furnaces is not a primary ore extraction facility such as a mine operation. As a beneficiation facility it utilizes ferrochrome recovered from slag material and high-grade chromite ore to manufacture a suite of medium to ultra-low carbon ferrochrome alloys for the steel market.

General Process Of Chrome Recovery Plant
Virtually all charge chrome plants now use the crushing/jigging process to recover chrome alloy from both stockpiled and currently produced slag. Studies were carried out at R and D Tata Steel to develop a flow sheet for the recovery of metal from metal–slag mix generated in its charge chrome ferrochrome with 50–60% chromium plant Bamnipal.

dependence on imports of ferrochrome. 3 SCOPE OF THE PROJECT Setting up a Chromite Beneficiation Plant will enrich the Chromite content of the ores liberate them from unwanted rock material and other minerals and eventually separate the final product into uniform grain sizes. In other words the purpose of beneficiation is to render the ore
High Carbon Ferrochrome Technology - ScienceDirect
The Xstrata plants at Lydenburg and Steelpoort Lion in South Africa are the only commercial large-scale high carbon ferrochrome plants worldwide utilizing a prereduction step. Chromite ore concentrate reductant typically coke but also char or anthracite and binder typically bentonite are proportioned and dried prior to milling.
OUR PROCESSES – Hernic
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.
