Abstract:
1. A process for preparation of slurries containing suspended and dissolved particles, said process comprising the following steps: a. providing a solution (A) of dissolved particles (A′), b. providing a slurry (B) of suspended particles (B′), c. introducing solution (A) and slurry (B) into a battery of hydrocyclone stages containing at least two hydrocyclone stages, wherein the solution (A) and the slurry (B) are separately introduced at different stages of the battery of hydrocyclone stages; and d. collecting a slurry (B″) containing at least a part of dissolved particles (A′) and at least a part of suspended particles (B′); wherein the collected slurry (B″) has a total dry matter concentration of the suspended particles (B′) and dissolved particles (A′) that is at least 3% higher than the combined dry matter concentration of solution (A) and slurry (B).
