High carbon ferrochrome is one of the most common ferroalloys produced and is almost exclusively used in the production of stainless steel and high chromium steels. Production takes place primarily in countries with substantial chromite ore supply. Relatively cheap electricity and reductants also contribute to the viability of high carbon ferrochrome. The most common production technology utilized is submerged arc smelting in AC furnaces, although open arc smelting in DC furnaces is becoming increasingly common. A more advanced technology route that includes a prereduction step is only utilized at significant scale by one producer. Production processes have become more energy and metallurgically efficient by utilizing advanced processes such as prereduction, preheating, agglomeration of ore, and CO gas utilization. Recently installed plants display manageable risks in terms of environmental pollution and occupational health.

Manganese ferroalloys are also manufactured by carbothermic reduction of manganese ores containing both iron and manganese oxides in submerged arc electric furnaces. The slags produced during the process contain significant amounts of manganese oxide; MnO and these slags can be reprocessed to ferrosilicomanganese (also called silicomanganese) and then to refined or low carbon (LC) ferromanganese or even to manganese metal.
