Claims (7)

1. Способ облагораживания кремнийсодержащих твердых остатков, полученных после выщелачивания меди из медьсодержащих остатков от прямого синтеза органохлорсиланов, отличающийся тем, что твердые остатки необязательно вместе с окисляющим агентом подают в плавильную печь, где остатки плавятся и образуют расплавленную металлическую фазу, по существу содержащую кремний и кальций-силикатный шлак, и отводят расплавленную металлическую фазу и инертный шлак из плавильной печи.1. The method of refinement of silicon-containing solid residues obtained after leaching of copper from copper-containing residues from direct synthesis of organochlorosilanes, characterized in that the solid residues optionally together with an oxidizing agent are fed to a smelting furnace, where the residues melt and form a molten metal phase essentially containing silicon and calcium silicate slag, and the molten metal phase and inert slag are removed from the smelter. 2. Способ по п.1, отличающийся тем, что остаток сушат и агломерируют перед подачей в плавильную печь. 2. The method according to claim 1, characterized in that the residue is dried and agglomerated before being fed to the melting furnace. 3. Способ по п.1, отличающийся тем, что остаток подают в плавильную печь в виде порошка путем впрыскивания через полый электрод или путем впрыскивания в расплав с помощью копья или через сопла, смонтированные в плавильной печи. 3. The method according to claim 1, characterized in that the residue is fed into the melting furnace in the form of a powder by injection through a hollow electrode or by injection into the melt using a spear or through nozzles mounted in a melting furnace. 4. Способ по п.1, отличающийся тем, что добавляют CaO и/или SiO2, и/или Al2O3 в качестве шлакообразующего материала, чтобы получить жидкий шлак.4. The method according to claim 1, characterized in that CaO and / or SiO 2 and / or Al 2 O 3 are added as a slag-forming material in order to obtain liquid slag. 5. Способ по п.1 или 4, отличающийся тем, что устанавливают основность, определенную как массовое отношение CaO/SiO2, 0,5 - 3,0.5. The method according to claim 1 or 4, characterized in that they establish the basicity, defined as the mass ratio of CaO / SiO 2 , 0.5 - 3.0. 6. Способ по п.1, отличающийся тем, что оксид металла или кислородсодержащий газ добавляют в качестве окисляющего агента. 6. The method according to claim 1, characterized in that the metal oxide or oxygen-containing gas is added as an oxidizing agent. 7. Способ по п.6, отличающийся тем, что в качестве окисляющего агента добавляют оксид железа. 7. The method according to claim 6, characterized in that iron oxide is added as the oxidizing agent.
