Calcite Concentrate Thickening

Calcite is NOT all that is needed in ALL applications. Thickening can be done by a number of methods including gelling or adding high molecular weight polymers. In slide 21 of the Lubrizol presentation, you will see you can add other AW/EP additives for increased load protection: Calcium Sulfonate Grease to Meet NLGI GC-LB

The influence of calcite concentrate as a filler and polyolefin elastomer as a modifier on the rheological and mechanical properties of compositions has been determined.

A brackish water reverse osmosis concentrate consisting of 4170 mg/L total dissolved solids (TDS) and a gypsum saturation ratio (SR) of 1.52, was treated to a volumetric recovery of 96.5% in a total recycle process utilising hydrated lime and CO 2 induced precipitation reactors and nanofiltration (NF) separation units. A chemical model that incorporates …

Although there is distinct variation in particle size distributions of 1, 2 and 4 h grindings of calcite concentrate, the effect on micro-graphite flotation was insignificant.The CaO content of the first calcite concentrate (54.9) increased to 55.5 in the final calcite concentrate (Table 2). This stage of flotation proved to remove not only ...

to the fact that the emulsifying eect of calcium stearate prevails over the thickening eect of the solid ller. However, the ... [19]. A calcite concentrate (CC) of grade 1TK (Ltd Tekhnokom, Ukraine), with an av-erage particle size of 2.5 µm, was used as a ller (the content of particles with a maximum size of 20 µm was 1.5%). CC

We show that a suspension of non-Brownian calcite particles in glycerol-water mixtures can be tuned continuously from being a yield-stress suspension to a shear-thickening suspension—without a measurable yield stress—by the addition of various surfactants. We interpret our results within a recent theoretical framework that models the rheological effects of …

A number of researchers investigated the so-called phenomenon of age-thickening or age-gelation in either concentrated (skim) milk or condensed sweetened milk (Noda et al., 1976; Snoeren et al., 1984; Aoki et al., 2002; Bienvenue et al., 2003).Their results indicated that preheating of milk, storage temperature, and TS content of the concentrate or whey proteins …

It has been established that the presence of calcite concentrate as a filler and propylene-octenoic block copolymers as a modifier in the composition helps to reduce its viscosity, which is due to the predominant effect of the emulsifying action of calcium stearate over the thickening effect of the mineral filler. An increase in the melt flow ...

Methodology for upgrading the rough concentrate: thickening (15 minutes in a 2-liter glass, water column height -190 mm), steaming in a water bath (time (t) – 60 min, T-85-90°C), two or three cleaning of the steamed concentrate (volume of cell 0.5-0.3-0.1 l, flotation for 5 min, T-20-25°C) and the scavenge flotation for10 min. Combinations of

In such cases it is necessary to thicken the slurry prior to flotation treatment for the overflow from the hydroclassifier will be quite dilute. In many cases it is possible to deslime ground lime rock and obtain an enrichment of calcite in the slime fraction.

Due to such submicroscopic graphite particles, the calcite concentrate produced from the Kurikka calcite marble by calcite–silicate flotation gives an average ISO brightness …
