9 Example 4 (Ex. 71): A geologist has collected 10 specimens of basaltic rock and 10 specimens of granite. The geologist instructs a laboratory assistant to randomly select 15 of the specimens for analysis. a. What is the pmf of the number of granite specimens selected for analysis? b. What is the probability that all specimens of one of the two types of rock are selected for analysis?

The flocculation value, or critical coagulation con- centration (CCC), is the minimum concentration of an electrolyte necessary to flocculate a given colloidal dis- persion in a given time (van Olphen, ).

Thus dis- persion occurs if the electrolyte concentration is less than the CCC. The modified triple layer model (TLM) of Leroy et al. [16] was used to compute the electrochemical properties of the Na-Mt particles as a function of the measured cation exchange capacity (CEC. This paper highlights hydrophobic flocculation applied to fine minerals and coal processing.

Initially, hydrophobic flocculation and its separation technology are briefly described. Then, several examples on the application of this technology to the beneficiation of Cited by: 4.
