Abstract
The invention relates to a method for mining and processing of an ore. The method comprises at least one mobile comminution device (26) comprising at least one mobile crusher unit and at least one mobile grinding unit located proximate to an ore body that is being mined (20), fragmented ore (22) from the ore body is comminuted in the mobile comminution device (26) to a size which can be readily pumped (28) without the use of special carrier fluids, preferably to a particle size p50 in the range between 0.05 to 1 mm and the comminuted ore is combined with water to form a slurry.
Claims22
A method for mining and processing of a rock ore, comprising the steps of:
- positioning at least one mobile comminution device comprising at least one mobile crusher unit and at least one mobile grinding unit, proximate to an ore body that is being mined and wherein the at least one mobile crusher unit and at least one mobile grinding unit are moved intermittently with advancement of the ore body that is being mined;
- comminuting fragmented ore in the at least one mobile crushing unit to a size in the range between 100 to 400 mm, and grinding crushed ore from the crushing unit in the at least one mobile grinding unit to a particle size p50 in the range between 0.05 to 1 mm;
- and
- forming a pumpable slurry of the comminuted ore by combining the comminuted ore with water in the absence of additional non-Newtonian carrier fluids;
- and
- pumping the slurry slurring in a pipe to a processing facility.
