System of workshop of copper mine ore dressing plant
From;    Author:Stand originally
Workshop of floatation of ore dressing plant of copper mine of hill of coloured wax gourd chooses sulfur exercise tank diameter is vitriolic add bit of vitriolic discharge to greaten suddenly, cause tank diameter ore pulp and vitriolic reaction aggravate, produce hydrogen of a large number of harmful gas vulcanization, the 4 people such as vermilion star, Fei Bin are choosing jockey near sulfur exercise tank diameter urgent processing when this problem in succession toxic faint, when the others of the class 9 people are in in rescueing a process, the 6 people such as Yang Ping, Chen Jun early or late toxic faint. So far, outside dying except 4 people, get hurt there already were 2 people to return to normal in 6 workers, 2 people still are guarded in serious illness, additional 2 people patient's condition is relatively stable.

In system of production of workshop of floatation of ore dressing plant of copper mine of hill of coloured wax gourd, need vitriolic use at choosing sulfur work, main effect to adjust ore pulp PH is worth, in order to satisfy sulfur floatation need. Those who use is chroma is of 98% thick vitriolic, add a place to be in tank diameter of the exercise that choose sulfur, vitriolic accretion introduces the dynamoelectric control valve of DN80. Vitriolic storage tank but store vitriolic about 80 tons, use conduit do as one pleases to come tank diameter of the exercise that choose sulfur. At present preliminary already eliminate a person to cause an accident to destroy; This system computer is independent not couplet net; Preliminary decide for system of automation of dynamoelectric control valve abrupt malfunction causes an accident, its reason remains to undertake technical appraisement further; Already sealed up for keeping to adding acid system to give at present.
