Document Type and Number:
WIPO Patent Application WO/2016/067652
Kind Code:
A1
Abstract:
Provided is an arsenic-elution suppression method capable of more stably suppressing the elution of arsenic from coal combustion residue. An arsenic-elution suppression method for suppressing the elution of arsenic from coal combustion residue by mixing and combusting multiple types of coal including a first coal having an arsenic concentration in mass ratio of 2.0 ppm or higher and one or more other types of coal different from the first coal, wherein the mixing is performed in a manner such that after mixing, the mass ratio P0 in the coal overall of the total amount of alkaline earth metals measured by oxide amount to the total amount of arsenic is 2,000 or higher.
