Titanium mine environmental protection

Resources of titanium (TiO ₂₎ forming a 94.3% vanadium and titanium present in the magnetic iron ore deposits. Vanadium-titanium magnetite iron, titanium, vanadium symbiosis, as well as cobalt, nickel, copper, gallium, scandium and other elements with multiple integrated value metal recovery Ore. By 1989 , about 75 % of the ore produced from the open mining had not been used for tailings and blast furnace slag; the main seven elements in the ore, except for the use of iron and the partial recycling of titanium and vanadium, cobalt and nickel. , gallium, scandium, although the recovered mineral iron, titanium concentrate, but not yet smelting can be recycled; low recovery of vanadium, titanium, in particular titanium mineral resource recovery is only 47%, 53.27% smelting recovery, The total utilization rate of titanium resources is only 25.04 %.
In order to improve the resource efficiency, economic benefits and eco-environmental benefits of the development and utilization of vanadium-titanium magnetite, one must greatly improve iron, titanium, vanadium and cobalt, nickel and gallium from the perspective of advanced and feasible process technology equipment and economical rationality. Comprehensive and comprehensive recycling of useful elements such as cesium and sputum, greatly reducing the total amount of waste, waste gas and waste water produced, and the discharge of the standard after scientific treatment, greatly eliminating environmental pollution; the second is to pay attention to the ecological environment of mining. Destruction, stability and safety of the slope of the stope, prevention of collapse and debris flow, and restoration and reconstruction of the ecological environment synchronized with mining; thirdly, attention should be paid to the environmental impact assessment of the stope, site selection, smelting plant, and overall construction of the living area. Reasonable layout, greening and beautification, improve the awareness of environmental protection of enterprises and employees, adhere to the " three simultaneous " system of designing, constructing, and putting into operation at the same time of project construction and environmental protection, so as to implement ideas, organize implementation, fund implementation, and technology. Implementation of equipment and implementation of feasible measures.
For the environmental protection of the development and utilization of ilmenite and rutile sand mines, the above principles, systems and requirements must also be adhered to. In particular, mining coastal sand mines should pay attention to the protection of coastal shelter forests, prevent coastal erosion, and timely rehabilitate and rebuild ecological environment after mining.
