Engineering And Chemical Considerations For Quality Control Of Metallurgical Wastes

General Statement In Montana, as in most states, the requirements for water quality control are becoming more restrictive. What was once accepted practice is now obsolete. The planning and construction of water quality control facilities has taken on new importance. Past practices and new ideas must be examined to meet the challenge. By this paper we hope to encourage the exchange of ideas for the improvement of water quality control techniques. Both the mining industry and governmental agencies should benefit from such an exchange. The following is a summary of the work done and in progress by The Anaconda Company in Butte to provide an improved water quality related to production processes. We invite your comments. Acknowledgements This paper would not have been possible without the efforts of many individuals and departments in The Anaconda Company, including the Environmental Engineering Department, Mr. Frank J. Laird, Director; Montana Operations, Mr. M. K. Hannifan, General Manager, and their assistants.
