Recovery of Metals from Aluminum Dross and Saltcake
Various aluminum-smelting by-products from three production sources were received and characterized. The waste materials were tested for compound identification and environmental acceptance. A coarse metallic aluminum recovery test using an Eddy Current separator (ECS) was performed using two different Circuit configurations. White dross performed equally well with either Circuit, while black d...

متن کاملRecovery of Metals from Electroplating Wastes
Disposal of metal finishing wastes is one of the most critical industrial waste problems in the United States today. Recent legislation greatly restricts the discharge of most heavy metals to watercourses and future discharge regulations may further restrict their release to the environment. Furthermore, interest in developing possible methods for reclaiming metals from plating waste streams is...
متن کاملExtraction and recovery of chromium from electroplating sludge.
This work reports a study of the extraction and recovery of chromium from the wastes (class I dangerous) generated by a galvanic manufacturer. Commercial HCl at room temperature was employed, and the conditions of the extraction process were optimized according to a sequential experimental design, which also included the acid concentration and contact time as variables. The best extraction cond...
متن کاملFactors Affecting Aluminum Dissolve from Acidified Water Purification Sludge
Recovering resources from water purification sludge (WPS) have been gradually stipulated in environmental protection laws and regulations in many nations. Hence, reusing the WPS is becoming an important topic, and recovering alum from WPS is one of the many practical alternatives. Most previous research efforts have been conducted on studying the amphoteric characteristic of aluminum hydroxide ...
