8. The smaller the fineness modulus, the higher the rock powders content will be. When the rock powders content is larger than 20%, the fineness modulus is smaller than 2.The content of rock powders in artificial sand changes along with the change of fineness modulus. When the rock powders content is lower than 17%, the fineness modulus is larger than 3. On the contrary, the larger the fineness modulus, the lower the rock powders content will be.

, by standard foundry practices, when making or casting the upper liner sections and no machining of these bevelled surfaces is required. 4 and 5, the upper liner section 14 is conically shaped opening downwardly and has concentric arcuate teeth 40 having bevelled ends 44., manganese steel.Referring again to FIGS. Furthermore, by using the method of the present invention, the usable life of the upper liner section 14 may be extended from two to five times longer than a single liner of the prior art.g. The upper liner section 14 is made from a softer material than the lower liners segments, e.g. The bevelled end 44 of teeth 40 may be manufactured by a conventional method, e.
For example, the haloacetic acid or its salt is chloroacetic acid or its salt, and R1 is -CH2CH2OH.represent -CH2COO"R*, where R* is defined above with respect to the first aspect of the first example embodiment.
Flocculant may also be added to this tank before the tailings slurry passes to the tailings thickener's feed well 215 at the centre of the tank. 2B, the thickener feedstock is initially discharged into a small diameter de-aeration tank 200 to allow any entrapped air in the slurry to be released.Referring to FIG.
