Method for handling a slag pot or ladle and pyrometallurgical tools

A method for handling a slag pot or ladle having a given temperature and having an inner wall and an outer wall, said method comprising the steps of

• a) spraying a mineral suspension on said inner wall, the temperature of said slag pot or ladle being greater than 100° C., so as to line said inner wall with a mineral layer, prior to the steps of:
• b) collecting a slag in said slag pot or ladle, lined on its inner wall with said mineral layer, of a gyro-metallurgical tool,
• c) transporting said slag pot or ladle from said pyro-metallurgical tool to a slag drop-off site,
• d) emptying said slag pot or ladle at said slag drop-off site in order to eliminate the slag contained in said slag pot or ladle,
• wherein step a) is performed with the purpose of putting into service said slag pot or ladle lined with said mineral layer in order to repeat steps b) to d), and
• wherein said mineral layer is a thin layer lined on the inner wall, having a layer thickness between 0.1 and 5 mm, and in that said mineral suspension comprises an aqueous phase and a mineral phase, said mineral suspension having a carbon hydrate content between 0.2 and 3% by weight relative to the total weight of said mineral suspension;
• and
• wherein said mineral suspension comprises one or several additives selected from the group consisting of dispersants, fluidifying additives and mixtures thereof, and wherein said dispersants and fluidifying additives are selected from the group consisting of polycarbonates, polyacrylates and polyphosphonates.
