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 natural graphite prices are predicted to increase in the next few days.

What is natural graphite used for?

Natural graphite is a refractory material with a high melting point of 3650 °C, and it is a good conductor of heat and electricity. Some of the applications for graphite include: batteries, lubricants, refractories, coatings and paint, metallurgy and moderator rods in nuclear power plants, among other applications.

Is natural graphite better than synthetic?

The increased use of silicon in anodes is still largely under development, but in future, if this technology is more widely adopted, natural graphite performs better than synthetic graphite with silicon in the anode.

How is natural graphite made?

Graphite is formed by the metamorphosis of sediments containing carbonaceous material, by the reaction of carbon compounds with hydrothermal solutions or magmatic fluids, or possibly by the crystallization of magmatic carbon.

What does natural graphite look like?

Graphite (/ˈɡræfaɪt/) is a crystalline form of the element carbon. It consists of stacked layers of graphene. Graphite occurs naturally and is the most stable form of carbon under standard conditions.

History of the use of natural graphite

In the 4th millennium BC, during the Neolithic period in south-eastern Europe, the Maritsa culture used graphite in ceramic coatings to decorate pottery.

Sometime before 1565 (some sources say as early as 1500), huge deposits of graphite were discovered on the road to Grey Knotts in the hamlet of Seathwaite in the parish of Borrowdale, Cumbria, England, which the locals found useful for marking sheep. During the reign of Elizabeth I (1558-1603), Borrowdale graphite was used as a refractory material to line the moulds of cannonballs, resulting in rounder, smoother shells that could be shot further, thus strengthening the English navy. This particular graphite deposit was so pure and soft that it could be easily cut into rods. Because of its military importance, this unique mine and its production were strictly controlled by the Crown.

During the 19th century, the uses of graphite expanded considerably to include furnace polish, lubricants, paints, crucibles, casting finishes and pencils, a major factor in the expansion of educational tools during the first great upsurge in popular education. The British Empire controlled most of the world's production (especially Ceylon), but production from Austrian, German and American deposits expanded in the middle of the century. For example, Joseph Dixon and partner Orestes Cleveland opened the Dixon Crucible Company in Jersey City, New Jersey, in 1845 in the Ticonderoga Lakes region of New York, where they established a processing plant, as well as a factory for the production of pencils, crucibles and other New Jersey products, as described in the 21 December 1878 issue of The Dixon pencil is still in production.

The beginning of the revolutionary froth flotation process was associated with graphite mining. The E&MJ article by Dixon Crucible contains a sketch of a 'floating tank' in the old process used to extract graphite. As graphite was light, the mixture of graphite and waste was fed into a final series of tanks in which a cleaner graphite 'floated' off, allowing the waste to fall off. In an 1877 patent, the two Bessel brothers (Adolph and August) of Dresden, Germany, took this 'floating' process a step further and added a small amount of oil to the tanks and boiled the mixture (stirring or frothing step) to collect the graphite, the first step towards the future flotation process. Adolph Bessel was awarded the Wohler Medal for his patented process to increase the recovery of graphite in German deposits to 90%. In 1977, the Association of German Mining Engineers and Metallurgists organised a special symposium dedicated to their discovery and to the 100th anniversary of flotation.

In the USA, Hezekiah Bradford of Philadelphia patented a similar process in 1885, but it is uncertain whether his process was successfully used in graphite deposits in nearby Chester County, Pennsylvania, a major producer in the 1890s. The use of the Bessel process was limited, mainly because of the discovery of large quantities of cleaner deposits worldwide that required only hand sorting to collect pure graphite. The most advanced technology, circa. 1900, is described in a report by the Canadian Department of Mines on graphite mines and mining when Canadian deposits began to become significant graphite producers.

At present, international supply chains were shocked, and logistics and transportation efficiency decreases. Geopolitical conflicts further aggravate uncertainties about the European and American economic recovery and the global commodity supply. For this reason, I assume the price of the natural graphite would not decrease significantly in the short term.
