Abstract
A visit was made to Cominco American, Inc., Bixby, Missouri to investigate their means of controlling possible hazardous working conditions for their employees involved in the beneficiation of lead ore. Approximately 4600 tons of ore were processed each day at this mill to produce lead, copper and zinc concentrates. Several of the control measures in place at this facility were state of the art including the use of isolated control booths for crushing, grinding, and flotation; good housekeeping program with a removal of dust on roadways and dock areas; use of binders sprayed over the lead concentrate pile stored in the open to prevent air erosion and contamination and oxidation of the lead-sulfide; use of a binder, vinyl latex emulsion, to cover zinc concentrate shipped on gondola car; use of a water spike to empty drums of cyanide and xanthate, and the lining of the truck bed hauling lead concentrates and other areas; use of an aspirator type vacuum system in the reagent room for dumping bags of starch to reduce dust; the use of wall insulation for temperature and noise control; and the use of an enclosed conveyor system. The author recommends that this facility be made a part of the in depth study of health hazards at lead ore beneficiation facilities so that a more detailed evaluation of the effectiveness of these control measures may be undertaken.
