Last replied to by SmartDog. Simple answer: yes 125 x 2.5 = 312.5.
In this process, the precipitation efficiency of heavy metal ions in the solution was largely affected by the activated degree of the raw CaCO 3, which is closely related to the rotation speed of ball milling.Accordingly, the removal results at different mill speeds from 0 to 400 rpm were shown in Fig. 1(a). Without wet ball milling (0 rpm), the lead-containing mixed solution …
G. Crapper, in Polymer Science: A Comprehensive Reference, 2012 10.29.4.3.4 Calcium carbonate. Calcium carbonate is mined from limestone and ground to size for use in coatings. It is also possible to obtain precipitated calcium carbonate that has a finer particle size distribution, and hence is more suitable in extremely smooth/high gloss formulations.
includes calcium, phosphate and a number of impurities, is mined, beneficiated (concentrated) and then sometimes ground dry or wet through the use of ball mills or rod mills. The rock is fed into an attack tank or reactor and reacted (digested) with sulfuric acid (H 2SO 4). An extremely simple representation of the digestion is as follows:
