1. A process of preparing a coal powder filter-cake, wherein the process comprises the steps of:
a. Providing a coal feedstock;
b. Conducting froth flotation on the coal feedstock;
c. Collecting of the floated coal product to provide a filter-cake; and wherein the filter-cake comprises:
an ash content of less than 2 wt %, based on the total weight of the filter cake; and
wherein the filter cake comprises a coal powder comprised of hydrocarbonaceous particles, wherein
at least 90% by volume (% v) of the hydrocarbonaceous particles are no greater than 100 μm (microns) in diameter,
at least 50% by volume (% v) of the hydrocarbonaceous particles are no greater than 50 μm (microns) in diameter, and
the hydrocarbonaceous particles have an average particle size by volume of at most 10 μm in diameter.
