Enhancing sedimentation performance of clarifiers/thickeners
Some mineral processing plants encounter difficulties in dewatering pulps using clarifier/thickener (C/T) equipment due to a layer of fine particles, air bubbles and chemicals formed at the top of the liquid in the thickener. Such layers are very stable and form a cap on the C/T. The dewatering performance of the C/T then deteriorates under these conditions, and a high percentage of solids is contained in the thickener overflow. A process for removing water from rock slurry containing a wide range of particle sizes in mineral processing operations has been developed. The process includes: (a) classifying the feed slurry into two size fractions, namely a coarse fraction and a fine fraction, (b) treating the fine fraction (and the coarse fraction if required) with a selected flocculant, and (3) thickening the flocculated slurry in sedimentation equipment to separate liquid from solids.

2 so as to reduce its propensity for blistering during and after construction. Still further, the selected bituminous mixture should have desirable fatigue resistance and should be substantially water-impermeable.
A method of selecting a bituminous emulsion with enhanced performance for paving is provided. This method includes selecting polymer modified bitumen with a penetration value of about 25 to 450 dmm at 25° C. and selecting one or more emulsifiers comprised of at least about 5% by mass of a cationic nitrogenous compound selected from compounds having a carbonyl carbon atom bonded to a nitrogen atom, compounds having a carbon atom double bonded to a nitrogen atom, or combinations thereof based on the total mass of the selected emulsifier. Each selected emulsifier is reacted with a carboxylic acid to create one or more carboxylate salts. Each carboxylate salt created from a different proposed emulsifier separately is mixed with the bitumen to form one or more proposed bituminous emulsions. The coalescence of each proposed bituminous emulsion is measured using a rheology test, and a bituminous emulsion of the composition described above is chosen for paving a surface based on its coalescence properties.
