Ferrochrome Slag Processing Nigeria Total

2.2 Ferrochrome slag products The ferrochrome slag products are granulated slag as well as classified slag products made by crushing and screening. The main part of slag is granulated. The cr ushed and screened slag products are produced from air cooled lumpy slag which is collected from various process phases, e.g. from ladles and launders.

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.

01-06-2014· Ferrochrome slag is a waste material obtained from the manufacturing of high carbon ferrochromium alloy. This slag is formed as a liquid at 1700 °C and its main components are SiO 2, Al 2 O 3 and MgO. Additionally it consists of chrome, ferrous/ferric oxides and CaO.

Ferrochrome (FeCr) is an alloy of chromium and iron containing between 50% and 70% chromium. The Producer of stainless steel & tool steel are the largest consumer of ferrochrome and charge chrome.It is chromium that confers upon stainless steel its remarkable corrosion resistance. Out of the total world chrome ore output about 95% is used to,

01-08-2019· Ferrochrome (FeCr) slag was used as a precursor for the synthesis of a geopolymer. The effect of KOH concentration, liquid solid ratio (L/S), content of potassium metalisicate (KS) or potassium aluminate (KA), curing time on the unconfined compressive strength (UCS) and metal leachability of the synthesised geopolymer was investigated. A 10 M

the slag was 2.6 percent during the period under study. An high silicon content in the alloy can reduce Cr2O3 dissolved in the slag by a silicothermic reaction and in turn the Si content of metal decreases, but this reaction is only significant at high Si contents. At this condition the colour of slag will become lighter.
