"A by-product of lead smelting is a matte which consists mostly of lead and copper sulfides. Experiments were conducted to determine the feasibility of removing lead from molten matte by adding iron as a reducing agent. The effectiveness of iron at 1000 and 1100°C was a function of matte composition, but not of temperature except near iron saturation. The lead content of matte could be decreased to as low as 9.0 to 11.6 wt pct (2.3 to 3.0 at. pct) at 1000°C, depending on composition. The effect of oxygen in the matte on lead recovery from iron-saturated mattes was also investigated. The addition of oxygen further decreased the lead content, and higher recoveries of lead were obtained"--Abstract, page ii.
