How to know natural graphite?

Recently, covid 19 outbreak spreads in Shanghai, China. There are more than 25,000 new asymptomatic domestic infections every day. China is implementing a dynamic zero-out policy. A leading respiratory expert said the key to COVID-19 prevention and control is to minimize transmission and fatality rate. Omicron has a low case fatality rate but is highly transmissible and can still claim many lives in large outbreaks. "Total openness is not applicable in China.  For China, we should keep to the dynamic zero-out and gradually open up."  

However, "dynamic zero clearance" is not the pursuit of complete "zero infection".  As the Novel Coronavirus has its own uniqueness and strong concealment, there may be no way to prevent the detection of cases at present, but rapid detection and prompt treatment must be carried out, as soon as one case is found, one case will be dealt with.  

The situation in Shanghai is serious. As the financial center of China, Shanghai is a very important city, and the outbreak of the epidemic in Shanghai will put a great impact on China's economy.  The current task is to contain the spread of the epidemic as soon as possible, to achieve social zero so that Shanghai's life and economy quickly return to normal.  

As China plays an important role in the global supply chain, the outbreak will have a significant impact on the supply and prices of many natural graphite.

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.
