| 摘要 |
Process and device for thermochemically drilling and separating SiO2 containing minerals by using such chemical compounds as fluxes in the combustion, which form in the melt silicates of low temperature melting range, primarily alkali metal silicates, the fluxes, mixed with catalysts and with metal powder serving as fuel, being passed through an oxygen lance or a core lance containing bundles of wires and ducts for passage of oxygen and flux at a high rate of speed, ignition being done semi-automatically or fully automatically. The use of the process and device according to the invention result in an increased effectiveness of the drilling and separation of the SiO2 containing minerals as compared to known thermochemical processes.
