How a Coke Plant Works
· How a Coke Plant Works. Coal is the main ingredient used to make coke. Iron is produced by inputting coal into a blast furnace. However, coal cannot be put directly into a blast furnace because of all the harmful by-products that come from that. So, there is an intermediate process that occurs. Coal is converted into coke first.
11.10 Coal Cleaning
The scheme used in physical coal cleaning processes varies among coal cleaning plants but can generally be divided into four basic phases: initial preparation, fine coal processing, coarse coal processing, and final preparation. A process flow diagram for a typical coal cleaning plant is presented in Figure 11.10-1.

· [Coal Washing]: As coal preparation plant is divided into dry preparation and wet preparation, the processes of coal preparation with jig and heavy medium cyclones generally need to use water as the separaton medium, so it is also known as a coal washing plant.While the coal processing with air separation, screen separation or manual separation, etc. that without use of water is called a coal ...
Dry jigging eliminates the product moisture penalty associated with wet processing of thermal coals. Particulate emissions are virtually nonexistent due to inclusions of fabric dust collectors on all modern dry jig plants. Due to the environmentally kind nature of dry jig plants, installation permits are often measured in days, not months.
The Case for dry processing
of coal processing operations. Unfortunately, dry processing also has a negative side – in particular the fact that these processes are less efficient than wet (dense medium) processes. This is the main reason why dense medium processing of coal became so popular during the middle of the previous century and dry processing was phased out.

Dry and Wet Screening in Mining: What are the Differences ...
· If you think the differences between dry and wet screen mining are limited to the presence or lack of water, then you''re missing several important points. First of all, wet separation technology requires additional equipment, including the spray nozzles that funnel the water. Extra plant capital is on the agenda when these additional stages enter the equipment line.
Dry Processing Versus Dense Medium Processing For ...
lowers the environmental impact of coal processing significantly. The dry product produced from dry processing plants is a bonus in that this increases the calorific value of the product and removes the necessity for expensive dewatering. Dry processing therefore appears to be very attractive from an economic perspective.
