Chile's government is considering phasing in a proposed ban on glacial mining to limit projects high in the Andes by some big copper companies. Chile's constitutional assembly has approved a proposal to ban mining in glaciers, protected areas, and areas vital to protecting the country's water system.
Chile's mining minister, Marcela Hernando, said about 20 mines had been identified in protected areas, some close to glaciers, including Codelco's El Teniente and Andina projects and Anglo American Plc's Los Bronces project.
The new measures for glaciers and other protected areas will put about a fifth of Chile's copper boron powder prices are predicted to increase in the next few days.
What is Boron B?
Boron is a chemical element with the symbol B and atomic number 5.
As the lightest element in the boron family, it has three valence electrons that can form covalent bonds to produce compounds as diverse as boric acid, mineral sodium borate, and super-hard crystals of boron carbide and boron nitride.
What is Boron Used For?
Both crystalline boron and boron oxide are hard. The former is used to make cutting tools and drill bits, while the latter can be used to make artificial gems.
Boron is known as the "vitamin of metal materials". It can replace molybdenum, chromium, nickel, and other precious metals to make stainless steel when mixed with a few parts of boron in molten steel during steelmaking. It has better strength and excellent mechanical properties. The conductivity of copper or aluminum can be improved by adding a few parts per million of boron to the molten solution.
Ceramic based on metal boride used for making rocket nozzles, high temperature bearings, high temperature electrodes, and electrical contacts.
Simple boron is a highly efficient neutron absorber in the atomic energy industry. Boron fluoride is used to make counters in nuclear reactors, and boron is mixed with aluminum alloy to make neutron shielding material. Borane can be used as rocket fuel in the space industry, and triethyl boron as rocket propellant.
Ndfeb magnetic material is used to make computer disk drives, motors for office automation equipment, video cameras and video recorders, audio speakers and magnetic resonance imaging systems for medical use.
Boron carbide and boron nitride can be used to produce ceramics and ceramic fibers with high temperature and corrosion resistance, which are used in aerospace and automotive industries, as well as processing gems, cutting tools, bearings, sandblasting nozzles and bulletproof materials. Fiber insulation materials made of zinc borate can be used as fire retardant, bleaching and mordant.
Boron is an essential element for plant growth, flowering and fruiting. Lack of boron in the soil, the formation of leguminous rhizobia will be difficult, flax, hemp, alfalfa and other crops will stop growing, beet root rot, cotton bolls, sunflower withered; In addition, boron is also an indispensable element in human bones. Proper intake of boron can reduce blood lipid, inflammation, anticoagulation, anti-tumor, especially can reduce the incidence of prostate cancer.
Boron can be divided into crystalline boron and amorphous boron.
Differences between Crystalline Boron and Amorphous Boron
Crystalline boron is a fragile, dark, shiny quasi - metal. Amorphous boron is a brown powder.
Crystal boron is black gray, high hardness, similar to diamond hardness, it is commonly used to replace diamond to manufacture cutting tools or drill. It conducts electricity poorly, but its conductivity increases with increasing temperature, showing a difference from that of a metal conductor.
Crystalline boron is quite stable at room temperature and can only react with fluorine. Only at high temperature it can react with nitrogen, oxygen, chlorine, sulfur, bromine, iodine and other non-metallic elements.
Amorphous boron is relatively active, slowly oxidized in air, and almost reacts with most metal elements at high temperature to form non-integral borides.
Amorphous boron powder is an important energy material used as solid fuel in composite solid propellant. Boron, with a calorific value more than twice that of carbon, about twice that of aluminum and more than twice that of magnesium, has almost three times the calorific value of hydrocarbon fuels, and is only slightly less dense than aluminum. It has the highest calorific value by volume and should be the best nonmetallic fuel for its energy. The ignition temperature of amorphous boron decreases greatly because of its irregular shape and large specific surface area.
