Description

Известен способ получени  свинца из его соединений путем восстановлени  водородом под высоким давлением и при высокой температуре .A method is known for producing lead from its compounds by reduction with hydrogen under high pressure and at high temperature.

Предложенный способ отличаетс  от известного тем, что восстановление свинца проводитс  при температуре 330-340°, то -есть выше температуры плавлени  свинца, что позвол ет получить свинец в расплавленном виде, упроща  тем самым технологический процесс.The proposed method differs from the known one in that the reduction of lead is carried out at a temperature of 330-340 ° C, that is, it is above the melting point of lead, which makes it possible to obtain lead in molten form, thereby simplifying the process.

Свинец восстанавливаетс  водородом из раствора -или пульпы, полученной из свинецсодержащего кека и концентрированного раствора едкой щелочи (60-80 г NaOH на 100 г воды) в автоклаве при высоких давлени х и температурахВ избытке щелочи РЬО,„в, получаема  по реакцииLead is reduced by hydrogen from a solution of pulp obtained from lead-containing cake and a concentrated solution of caustic alkali (60-80 g of NaOH per 100 g of water) in an autoclave at high pressures and temperatures. An excess of alkali PbO, is obtained by reaction

раствор етс  с образованием плюмбита натри . При высоких температурах плюмбит натри  раствор етс , и из раствора этой соли свинец восстанавливаетс  водородом по реакции:dissolves to form sodium plumbite. At high temperatures, the sodium plumbite dissolves, and from the solution of this salt lead is reduced by hydrogen by the reaction:

Na.PbO, - HS Pbf,,,j „„-„ - 2 Na ОН,,Na.PbO, - HS Pbf ,,, j „„ - „- 2 Na OH ,,

Одновременно регенерирует щелочь, св занна  в ллюмбите натри . В зависимости от температуры з автоклаве свинец получаетс  в виде порощка (при температуре ниже 327°) или в виде жидкого металла (при температуре выще 327°).At the same time, it regenerates the alkali associated with lumbite sodium. Depending on the temperature in the autoclave, lead is obtained in the form of powder (at a temperature below 327 °) or in the form of a liquid metal (at a temperature higher than 327 °).

Окислы железа и другие компоненты пустой породы (кроме кремнекиСлоты и окиси алюмини ) остаютс  в неизменном виде или частично восстанавливаютс  до низших степеней окислени . В металлическую фазу переход т также золото, серебро и некоторое количество других компонентов (олова, висмута, сурьмы, мышь ка).Iron oxides and other components of waste rock (except for silicate Slots and aluminum oxide) remain unchanged or partially reduced to lower oxidation states. Gold, silver and some other components (tin, bismuth, antimony, mouse) are also transferred to the metal phase.

При 330-340° металлический свинец скапливаетс  -на дне автоклава в жидком виде. Этим устран ютс  неэффективные операции 127413- 2 делени  порошка металлического свинца от твердых компонентов пустой пoipoды и создаетс  возможность осуществлени  непрерывного процесса. Общее давление в автоклаве составл ет 100-200 атм. Длительность восстановлени  равна нескольким минутам. При температуре выще производить процесс не следует из-за резкого возрастани  общего давлени .At 330-340 ° C, metallic lead accumulates at the bottom of the autoclave in liquid form. This eliminates the inefficient steps 127413-2 of dividing the metallic lead powder from the solid components of the empty powder and makes it possible to carry out a continuous process. The total pressure in the autoclave is 100-200 atm. The recovery time is several minutes. At a higher temperature, the process should not be carried out due to a sharp increase in the total pressure.
