Integrated System for Metal Recovery Kinefico Engineered Systems Inc. Newbury, Ohio

Kinetic0 Engineered Systems Inc. announces its new IonWinner, the first integrated system combining ion , exchange and electrowinning for metal recovery, waste :: minimization, and environmental compliance. The Ion- -* Winner is designed to boost plate-out efficiency, provide faster batch time, and recover copper, tin-lead, precious metals, and a variety of other metals. The system will reduce levels of hazardous metals in concentrated wastes to meet stringent discharge limits for printed circuit board and metal-finishing processes. This versatile design eliminates the need to invest in two systems, thus saving money and minimizing floor space required for installation. The electrowinning process reclaims metal from ion exchange regenerations and spent chemistries, thereby reducing hazardous sludge and producing scrap metal for resale or nonhazardous disposal. The system also features selective pollution control resins.

Electrolytic Recovery Equipment Covofinish Co. Inc. North Scifuafe, RI.

Covofinish introduces the COVO-SP line of electrolytic recovery equipment, which fea- tures a unique, high surface area, mobile cathode that does not require scraping of the deposited metal. These new units are very compact while offering large re- covery capacity. They are availa- ble for both precious and com- mon metals and range in recov- ery capacity from one ounce per day to pounds per day. The COVO-SP line sets a new stan- dard for electrolytic recovery in ease of use, size, performance, and price.
