Utilization of non-coking coal Non-coking coal can be used as a reductant in the ITmk3 ® Process. Non-coking coal is abundant all over the world and low in market price compared with coking coal used by blast furnaces. Flexible operation ITmk3 ® is a simple process that uses conventional equipment. Therefore, plant operation is quite easy.
Jul 30, 2018· The coking coal resources can be augmented by recovering extra low ash coking coal from washery middlings by suitable beneficiation processes (Jha, 2012).This possibility has been established from tests. The middlings were crushed to 13 mm and 3 mm and thereafter subjected to float and sink tests. The results are presented in Figure 10.0 (a).
Apr 12, 2016· The Coal Recovery and Cleaning by Flotation Flowsheet Diagram. The above flowsheets are based on existing small coal flotation plants. They illustrate clearly the simplicity and feasibility of adding "Sub-A" Coal Flotation as an additional process to small washing plants.
Coking Coal LLC is focused on the production and sales of high-quality metallurgical coal products utilizing best practice environmental standards. Coking Coal LLC is owned by Coking Coal Pty Ltd, an Australian coal exploration and development company.
Coking plant. Coal is needed when producing liquid hot metal in the blast furnace. However, we cannot utilise coal directly in the blast furnace as it contains a lot of harmful and unnecessary by-products. Coal is furthermore not strong enough to carry the blast furnace load. This is why we start by converting our coal into metallurgical coke.

The blended coal mass is heated for 12 to 20 hours for metallurgical coke. Thermal energy from the walls of the coke chamber heats the coal mass by conduction from the sides to the middle of the coke chamber. During the coking process, the charge is in direct contact with the heated wall surfaces and develops into an aggregate "plastic zone".
As the temperature of the coal increases, it becomes plastic, fusing together before resolidifying into coke particles. This is known as the caking process. The quality of the resultant coke is determined by the qualities of the coking coals used, as well as the coke plant operating conditions.
