The method of contact angle measurements and estimation of work of adhesion in bioleaching of metals.

摘要: In this paper, we present our method for the measurement of contact angles on surface minerals during bioleaching process because standard deviation obtained in measurements achieved unexpectedly low error. Construction a goniometer connected with specially prepared computer program allowed us to repeat several times over short time course, yielding excellent results. After defining points outline image drop and its baseline as well first approximation drop, an iterative is initiated that aimed at fitting model baseline. turn, after medium which were made, work adhesion determined according Young-Dupre equation. Calculations made use two methods named L-M L-Q methods.
