| titleOfInvention | A kind of environment-friendly and energy-efficient normal temperature and pressure wet processing is prepared the method for smart bismuth |
| abstract | The invention discloses a kind of environment-friendly and energy-efficient normal temperature and pressure wet processing and prepare the method for smart bismuth, comprise normal temperature leaching, liquid-solid separation, electrodeposition, alkali fusion, electrowinning process, specifically comprise: at normal temperatures and pressures, bismuth oxide, bismuth concentrate or copper bismuth concentrate are placed in to acid chlorine salt system, make oxidant with air or oxygen, normal temperature leaches; Separation of Solid and Liquid, leachate is directly sent into swirl electrolysis device at normal temperatures and pressures, controls DC voltage 1 ~ 3.5V, current density 150 ~ 800A/m 2 Condition under, electrolysis 1 ~ 7h obtains liquid and sponge bismuth after the electrodeposition of clarification, after electrodeposition, liquid returns to leach in operation and recycles; The sponge bismuth that electrodeposition obtains covers melting with alkali and obtains thick bismuth; To after thick bismuth electrolysis, obtain smart bismuth. The present invention at normal temperatures and pressures, utilize air or oxygen to carry out Oxidation Leaching to bismuth mineral in acid chlorine salt system, adopt eddy flow electrodeposition directly to extract bismuth from leachate electrodeposition, the present invention can be completed at normal temperatures and pressures, and the present invention is easy and simple to handle, bismuth mineral leaching rate is high, cost is low and environmental protection. |
