Introduction of Anthracite to Indian Ferro Alloy industry for the first time in 2003 as a reductant resulting in major cost reduction. Usage of Bentonite in Chrome ore briquetting in 2001 as an alternative to lime for quality improvement. Utilization of 55% High Manganese slag in silico Manganese operations.


Anthracite is an unbeatable reductant for glass, water filtration medium, and colourant, on top of many lesser-known applications. Its versatility comes from possessing the highest carbon content of any other coal or material available, which makes it perfect for colouration, redox, burning, filtration, and much more.

10%The effect of biochar substituted for anthracite as reductant on magnetizing-roasting pyrite cinder was investigated. The key of magnetizing-roasting is the gasification reaction between reductants and CO2. Since biochar could react with CO2 more rapidly at lower temperature, the reactivity of biochar is better than that of anthracite.


The global high-grade anthracite market is projected to grow at a CAGR of 4.2% by 2028. This growth can be attributed to the growing demand for the product in the chemical industry, cement industry, and steel industry. The product will also witness increasing demand from countries such as India and China due to their rapid industrialization and ...


While the target has been set, the steel makers globally are yet to deploy commercially viable large scale steelmaking processes by using hydrogen as a reductant to make steel from iron ore instead of coking coal. The production of hydrogen also needs to be from a green energy source instead of traditional ones to actually reduce carbon footprint.


These results show that valuable products can be achieved by controlling the type and amount of the reductant such as (1) low carbon steel containing 0.17 wt% C, 0.05 wt% S, and 0.01 wt% P (steel number 10), (2) low carbon high sulphur steel which can be used as free cutting steel by adding the adjusting Mn at tapping (steel numbers 1 and 2 ...


All of the anthracite used in the U.S. is produced domestically by American workers. Almost all of the nation's anthracite is found in Northeastern Pennsylvania. There are over seven billion tons of anthracite available for mining. It is a solidly proven fuel source and high carbon reductant that is widely available through


As shown in Fig. 4 (a), when anthracite was used as a reductant, a broad band indicating the presence of glass phase materials was observed between 10° and 40° in XRD patterns. Therefore, it could be inferred that there was certain amount of liquid phase formed in the briquettes during reduction process.
