Type 2 cement is still a general cement, but it has resistance to sulfates and heat of hydration. Type 3 cement is for high strength properties in the early stages of the cement''s life., immediately after curing. Type 4 cement is used where very low heats of hydration are desired.
Chromite ore can be mined to produce chromite concentrate. It can also be crushed and processed. Chromite concentrate, when combined with a reductant such as coal or coke and a high temperature furnace can produce ferrochrome. Ferrochrome is a type of ferroalloy that is an alloy in between chromium and iron
With low electricity prices, South Africa has been able to expand chromite and ferrochrome production more or less continuously since the AOD process was developed in the 1960s to use ferrochrome smelted from lowergrade ores. Samancor was created in .
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, from ladles and launders.
