Technical Field

Background

At present, the multi-metal smelting process needs to crush ores to about 200 meshes, and then the ores are made into pellets through flotation and magnetic separation and then are smelted in a furnace. Not only consumes a large amount of ore dressing investment, electric charge, water charge and labor charge, but also causes serious pollution to the environment. The main component of many minerals is mainly silicon dioxide, taking vanadium-titanium magnetite as an example, every 1 ton of crushed ore can magnetically separate 15 wt% of iron powder, which is rich ore, more than 80 wt% of iron powder is silicon-magnesium-calcium, the total content of vanadium and titanium is about 2 wt%, and the separation of vanadium and titanium is very difficult, and 75 wt% of vanadium and titanium can be obtained only by multiple purifications by sulfuric acid method and electrolytic method.

The traditional metallurgical technology is from mining, smelting in a furnace and deslagging again, common metal deposits are formed by mixing several or even dozens of different elements, and almost no pure metal deposits exist, so that ores which are dozens of times of blasting are caused in mining, and great investment is used for mineral separation. The inventors have also found that metallurgical slags are typically water quenched to cool with thousands of temperatures, and if used as glass ceramics are of course heated to more than a thousand degrees celsius. And if a metal melting furnace and a glass-ceramic melting furnace are connected, depending on the density of metal and glass, do not allow layered outflow? After a decade of experiments, the inventor finally developed a new process and a new apparatus that can simultaneously produce 3 kinds of metals with different densities and high-performance glass ceramics.
