Abstract

L'invention décrit un procédé de traitement du minerai pauvre de charbon en vue de le rentabiliser. On brûle ce minerai pauvre dans un dispositif de combustion à phase dispersée, à une température à laquelle la cendre forme un laitier; on enlève le laitier qu'on traite de façon analogue à du laitier de haut fourneau. On peut ainsi produire de l'agrégat pour béton ou de la matière concassée pour servir à la construction de routes, à former des milieux de filtration ou à constituer du ballast pour voie de chemin de fer.The invention describes a process for treating lean coal ore with a view to making it profitable. This lean ore is burned in a dispersed phase combustion device, at a temperature at which the ash forms a slag; the slag is removed and treated in a manner analogous to blast furnace slag. Concrete aggregate or crushed material can be produced for use in road construction, filter media, or railroad ballast.
