optimize the production process

Strengthening energy saving. Backward smelting, processing capacity , and vigorously promote the application of  machine for pellets  and equipment, and optimizing the production process , strengthen energy management . Focus on the promotion of new cathode structure electrolytic tank, aluminum and other advanced energy efficient cryogenic technology .
Promote oxygen bottom blowing smelting technology , flash technology widely used. Accelerate the process of continuous short lead smelting , refining of liquid lead and lead slag direct reduction technology development and application. Encourage hot charging , direct casting .
Promote smelting slag , waste gas , waste water and waste heat utilization . Promote smelting slag from extracting valuable components extracted from the red mud recycling iron , precious metals,  oil equipment , etc., from copper smelting slag, anode slime extract rare metals , lead and zinc smelting slag extracted from cadmium , germanium, iron, etc., from gold slag and tailings cyanide to extract copper, silver and lead. Promote the comprehensive utilization of waste smelting , recycling the mother liquor from the alumina gallium, scandium , and nickel recovery from the electrolyte . To promote recovery of the exhaust gas from the smelting of lead , zinc, copper , antimony , bismuth and sulfur , and phosphorus. Strengthen waste heat utilization and smelting waste water recycling .
