Chromium, primary/virgin

6.8

Description

The module describes the production of chromite for a world-wide production average. It is designed for the use of chromite as intermediary product in the production of ferrochromium, dichromate and refractories. This module does not consider secondary sources of chromium. Process data is taken mainly from a material flow analysis for the con-sumption of chromium compounds in Germany. Results are used as a proxy for the European situation. This activity includes the pre-treatment of the ore, the direct reduction to high-carbon ferrochromium via ordinary and new technology, the transport of disposal slag and cake, and the treatment of effluents in a communal wastewater treatment plant.
