ca. 1978. ASARCO plant. In the center of this early 1978 photograph of the American Smelting & Refining Co. plant located in Ruston is the Herreschoff Roaster baghouse that was brand new that year. It had been installed as part of ASARCO's modernization and served to curb industrial air pollution. The baghouse vented the roaster plant to the left. The arsenic plant is situated on the right. The gondola cars collected "calcine" from the arsenic roasters which was further processed. (Additional information provided by a reader) Photograph ordered by National Blower & Sheet Metal Co.
