Abstract
Scale inhibitors and slow-release polymers were tested by the Bureau of Mines at mine drainage treatment facilities. The scale inhibitors were investigated to determine their effectiveness in controlling gypsum (caso4) scale; the polymers were investigated to determine their effectiveness for increasing settling rates of suspended iron hydroxide. Two types of scale inhibitors were tested at a site having a severe caso4 scaling problem. Both proved to be effective in controlling scale formation; in addition, one caused the dissolution of caso4 deposits. Slow-release polymers were tested at three mine drainage treatment facilities. These gelatinous polymeric flocculants were found to be convenient and easy to use, but only effective when ph could be controlled.
