Coal is the dominant fuel in China to provide primary energy, and 70% of polyvinyl chloride
is produced from coal-based CaC 2. CaC 2 reacts with water to produce acetylene and …

This work provides a comprehensive review of research on the cold-bonding pelletization
process used to produce lightweight aggregates (LWAs) using waste materials, to valorize …

Low-grade iron ores are finely ground and processed to recover iron-bearing minerals.
However, the iron-rich powder is too fine to be used directly in blast furnaces and most direct …

In this study, the effects of K 2 CO 3 addition (0, 1, 2 wt%) on the physicochemical properties
(moisture content, liquid saturation, plastic deformation degree, drop number, compressive …

The addition of pellet binders often represents a compromise between the pellet grade and
quality measures as strength, reducibility, and dustiness. Each inorganic compound present …

Coke is the only raw material that descends into the lower part of the blast furnace (BF) in its
original form; therefore, it is of utmost importance to improve the coke properties for its use in …

The use of iron ore–coal composite pellet as a raw material for iron making is an ongoing
area of research. Investigations on composite pellet reduction have reported some …

Due to its high carbon and low impurities contents, as well as good reactivity, biochar can
partly or totally replace coal or coke as a promising reducing agent in metallurgy. This study …

Pellet ore not only has excellent metallurgical and mechanical properties, but is also an
important metallurgical raw material used to solve the problem of increasing depletion of …

The beneficiation and valorization of coal fines is an important element that has to be
considered in coal waste management. This review aims to assess the potential ecological …
