Operation Of The CONTOP Process At The Asarco El Paso Smelter

In 1993, the El Paso Smelter began operation of the first commercial CONTOP copper smelting furnace. The CONTOP process was chosen for the plant modernization due to its low capital cost and the ease that it could be incorporated into a 100 year old existing smelter. After four years of operation, CONTOP has proved itself to be a reliable copper smelting technology. This paper will discuss a brief start-up history, current operation, and future modifications and improvements.
