Aluminothermic method Aluminum is used as a reducing agent, and is smelted by a lower ignition method in a furnace drum of an alkali lining. A small portion of the mixed charge is first charged into the reactor, i.e., ignited. After the reaction started, the remaining charge was continuously added. Typically high for smelting iron vanadium (vanadium containing 60 to 80%), recovery is slightly lower than the silicon thermal power, from about 90 to 95% vanadium and iron drill often has isomorphic respectively occur in Titanomagnetite And pyrite. The beneficiation of such ore is generally to first extract the vanadium iron concentrate by weak magnetic separation, and then recover the ilmenite from the tailings by re-election, strong magnetic separation, flotation and electric separation, and recover by flotation. Pyrite. The titanium contained in the vanadium iron concentrate is not removed by beneficiation and can be separated in smelting. In order to meet the necessary slag amount for high-titanium slag iron making, it is sometimes unreasonable to excessively increase the iron grade of vanadium-iron concentrate. The process of recovering titanium from magnetic separation tailings must first ensure that high quality titanium concentrate is obtained. Various processes such as re-election, flotation, re-election and flotation, re-election of a strong magnetic separation, flotation, and re-election of a strong magnetic separation were studied. The ilmenite concentrate is electrically selected to increase the grade of titanium dioxide to over 48%. The flotation of ilmenite is carried out in acidic pulp. The recovery of cobalt from flotation pyrite should be carried out before flotation of ilmenite. If the ore contains carbonate minerals, it must be floated beforehand. Sedimentary vanadium-bearing carbonaceous slate is also an important one in China's vanadium resources, and is still in the research stage. Vanadium in the ore disseminated in particulate minerals such as mica or vanadium adsorbed state exists, with processing methods difficult enrichment, thus studied hydrometallurgical vanadium. The ore is first calcined to remove charcoal, followed by sodium roasting and water leaching. After the water leaching residue, acid leaching can further increase the leaching rate of vanadium. Sometimes the raw ore is firstly integrated into the vanadium-containing coarse concentrate by flotation, and then calcined and leached, which can significantly reduce the acid consumption.

The loader is an earth-rock construction machine widely used in road, railway, construction, hydropower, port, mining and other construction projects. It is mainly used for shovel loading bulk materials such as soil, sand, lime, coal, etc. Hard soil, etc., for light shovel. Different auxiliary work devices can be used for loading and unloading of bulldozers, lifting and other materials such as wood.

In the construction of roads, especially in high-grade roads, loaders are used for the filling and excavation of subgrade works, asphalt mixing materials and aggregate and loading of cement concrete yards. In addition, you can carry out operations such as pushing soil, leveling the ground, and pulling other machinery. Because the loader has the advantages of fast operation speed, high efficiency, good maneuverability and light operation, it has become one of the main types of earth and stone construction in engineering construction.
