grinding tonnages produced for ferrochromium

Ferrochromium is an alloy which contains or consists of 20 to 70% chromium, 0.02 to 10% carbon, and the rest iron as well as the usual impurities. Ferrochromium is formed through a melting reduction of iron-containing chromium ores, especially chromium iron ore, with coal according to the equation FeCr 2 O 4 +4C=Fe+2Cr+4CO

    Implementation of industrial waste ferrochrome slag in

    Jun 01, 2014 The slag production is 1.1–1.6/t of Ferrochromium alloy depending on feed materials . Ferrochromium is a master alloy of iron and chromium. In high carbon ferrochromium, metallic Cr content is 60–65% with varying amounts of Fe and C. Ferrochromium is produced pyrometallurgically by carbothermic reduction of chromite ore (FeO Cr 2 O 3). The

    Ferrochromium slag remains as a waste among others in the production of ferrochromium metal. The slag was prepared as aggregate by crushing and grinding it in a laboratory mill to particle size smaller than 100 micron for brick production. The clay raw material was obtained from a brick manufacturer ( Yıldız Tu gla) in Bartin, Turkey

    Jul 16, 2007 Ferrochromium, the master alloy of iron and chromium, contains 45–80% Cr with various amounts of Fe. It is produced by carbothermic reduction of chromite ore (FeO Cr 2 O 3 ). The ferrochromium slags consist mainly of SiO 2 , Al 2 O 3 and MgO in different phases and smaller amounts of CaO, chromium and iron oxides and metal fragments

    Preparation and characterization of green glazes using

    Jul 23, 2020 Green glazes were successfully prepared using ferrochromium slag waste as chromium and iron precursors by introducing Co2O3 as coloring agent. The performance of the glazes was investigated by XRD, EDS, FT-IR, and UV-vis. A chromatic mechanism was proposed to explain the variation of glaze colors with the increase of Co2O3 content. The results showed that the Co-doped

    Low-carbon (LC) ferrochromium is typically produced by fusing chromium ore and lime in a furnace. A specified amount is then placed in a ladle (ladle No. 1). A known amount of an intermediate grade ferrochromesilicon is then added to the ladle. The reaction is extremely exothermic and liberates chromium from its ore, producing LC ferrochromium
