Description
Измельченна природна киноварь или другие соединени ртути помещаетс в железный электролизер с изолированными внутри стенками. Дно электролизера , покрытое слоем ртути, вл етс катодом. Лноды могут быть магнетитовые или платиновые. Электролитом служит насыщенный раствор поваренной соли. Электролиз ведетс при сильном перемешивании с анодной плотностью тока около 0,2 R/cM при температуре 40 - 50. После исчезновени красной окраски киновари раствору дают отсто тьс , прозрачный электролит сливают (онможет быть использован дл следующего элек тролиза ). Осадок над ртутью промывдют ,водой и электролизер наполн етс 40%-м раствором сернокислого аммони . В этом растворе проводитс электролиз при температуре 40-50 с катодной плотностью-тока на ртути около 0,2 . ЭлектроЛИЗ ведетс до полного выделени на катоде ртути из раствора. Сера киновари частично сгорает, частично получаетс в свободном виде, плавающей в растворе. По сравнению с пироиеталлургическим способом получени ртути предлагаемый способ вл етс в значительной мере менее довитым и более эконо мичным. Предмет изобретени . Способ получени ртути из руд электролизом , отличающийс тем, что руду подвергают электролизу с ртутным катодом сперва в насыщенном растворе поваренной соли, а затем в растворе, сернокислого .The crushed natural cinnabar or other mercury compounds are placed in an iron electrolytic cell with insulated walls inside. The bottom of the cell covered with a layer of mercury is the cathode. Lnod can be magnetite or platinum. Electrolyte is a saturated solution of salt. Electrolysis is carried out with vigorous stirring with an anodic current density of about 0.2 R / cM at a temperature of 40-50. After the cinnabar has disappeared red color the solution is allowed to stand, the transparent electrolyte is drained (it can be used for the next electrolysis). The precipitate over mercury is washed with water and the electrolyzer is filled with 40% ammonium sulphate. In this solution, electrolysis is carried out at a temperature of 40-50 with a cathode current density on mercury of about 0.2. Electrolysis is carried out until complete release of mercury from the solution on the cathode. Cinnabar sulfur partially burns, partially obtained in free form, floating in solution. Compared to the pyroiethallurgical method of mercury production, the proposed method is significantly less toxic and more economical. The subject matter of the invention. A method of producing mercury from ores by electrolysis, characterized in that the ore is subjected to electrolysis with a mercury cathode, first in a saturated solution of common salt, and then in solution, sulphate.
