Minor-element behavior and interaction in the copper matte-iron silicate slag system have been studied by the Bureau of Mines. In the present work, the possibility of interactions among the minor elements as, sb, bi, se, and te was investigated. Equilibrations of matte, slag, and one of each of the five minor elements were performed at 1,250 deg c under typical matte smelting atmospheres of CO, co2, and so2 for mattes containing 40, 50, and 60 pct cu. Results are compared with those of a previous Bureau of Mines study in which all five minor elements were present simultaneously.
