Abstract

The invention belongs to the technical field of gold tailing processing, and concretely relates to a gold tailing granule, and a use thereof in the preparation of a locomotive brake shoe friction material. The gold tailing granule prepared from existing gold tailing wastes through a specific gold tailing processing technology can be used for preparing the rail locomotive brake shoe friction material, the performances of a locomotive brake shoe produced from the friction material can meet requirements of the locomotive brake shoes, the obtained brake shoe has a high high-temperature friction coefficient, and the friction performance at a high temperature is stable, and is suitable for demands of the locomotive brake shoes.

Description

technical field [0001] The invention belongs to the technical field of gold tailings treatment, and in particular relates to a gold tailings particle and its application for preparing friction materials for locomotive brake shoes. Background technique [0002] In the history of more than 5,000 years of civilization in my country, gold has been used for more than 4,000 years. Like Egypt, India, and ancient Rome, it has become one of the first countries in the world to use gold and other alloys. Gold ranks 79th in the periodic table of chemical elements, its atomic weight is 197, and its density is high (19.32g / cm 3 ) but lighter than platinum. The color of gold is golden yellow, and it has good ductility. 31.25g of pure gold can be hammered into a gold leaf with a thickness of 1 / 10,000th of a millimeter, which can cover 9m 2 area. The volatility of gold is small, and the volatile amount of melted gold is insignificant under normal circumstances. Gold has good electrical a...
