Technological and ecologican contributions concerning the circulation of liquid phase in the cyanidation process of pyrites with gold content

摘要

In the technological processes of dissolution by cyanidation for the gold from auriferous pyrites, are used polluting but unreplaceable substances. In the paper are presented the results obtained at the optimization of the technological process and in this way finally the removal of some polluting agents in the external environment. One of the main parameters which is monitoring the technoligical process is the average transitory time of the liquid phase with solid suspension. In the paper are presented the results obtained in the technological process of cyanidation installation from Dressing Plant Sasar-Baia Mare. In order to eliminate the errors of measurements, the marking was done using two colouring tracers, the rhodamine B (tetraethilchlorhydrate of rhodamina) and the uranine.
