Abstract: A Bayer process includes contacting bauxite and calcium fluoride with sodium hydroxide and forming a slurry, with the calcium fluoride may provide at least 1 wt. % of the calcium added to the process, and precipitating alumina from the slurry.

Abstract: A pressure-fit grinding pad assembly and a method of constructing same and connection to a grinding pad of a floor grinding machine or other suitable type grinding machines is described. The grinding pad is formed by an abrasion head of abrasion material which is immovably bonded on a metal attachment base which is shaped for pressure fit connection to a mounting base and wherein its removal therefrom requires it to be pressure punched with adequate force. The mounting base can be a steel plate shaped for connection to retainers secured to or formed in an outer surface of a grinding disc or may be constituted by holes formed in the top surface of the grinding disc. The mounting base can be formed integrally with the attachment base of the grinding pad for connection to the retainers.
