EU puts forward list of most important mineral resources

In the September issue of the European Commission's Corporate Directorate, it published a research report on the determination of key mineral materials jointly completed by experts from member countries' relevant departments, geological surveys and related industrial fields. The report analyzed the 41 types of minerals and metals and other raw materials, and finally identified 14 of them as the most important for the EU. They were: yttrium, yttrium, cobalt, fluorspar, *, yttrium, graphite, indium, magnesium, antimony, Platinum, rare earth, antimony, and tungsten. The report pointed out that the demand for these raw materials supply risk mainly lies in: First, some of them are aggregated in the global distribution, such as China has 90% of the world's rare earth and antimony, Brazil has 90% of the world's antimony, and 77% of platinum. Produced in South Africa; the second is the negative impact of the mining process on the environment. In order to actively respond to the tense problem of key mineral materials, the report recommends that the first is to strengthen the research and use of recycled materials; the second is to pay close attention to the international trade and investment trends of relevant products; the third is to find alternatives to key mineral materials.

Center Drill Bit

Center Drill Bit is also known as Slocombe Drills, Centre Drills were originally designed to create the countersink required to locate a tailstock centre when turning between centres. They have a point angle of 60° to match the angle of a Tailstock Centre.
A Centre Drill can also be used to provide a start location for a drill when drilling down the centre of a bar held in a Lathe chuck. Centre Drills are short and rigid enough to mark the bar centre without wandering off if they are carefully offered up to a rotating work-piece.
