Abstract
A method is provided in which solids, such as run-of-mine ore, are crushed and reacted with a liquid within a mass flow reactor as a substantially continuous process. The reaction can include dissolving at least one material out of the crushed solids and into solution with the liquid. Solid and liquid materials migrate through and are extracted from the mass flow reactor substantially under the influence of gravity alone and without the use of other relevant driving means or forces. The respective flows of solid and liquid materials through the mass flow reactor can be controlled so as to maintain generally constant levels of each therein. At least some of the reaction can occur under a predetermined hydrostatic head of the liquid. Further processing of the solid and liquid materials can be performed, including isolation of at least one material of interest extracted from the crushed solids.
