Production of synthetic slag used in the production of cement clinker comprises adjusting silicate limestone and/or flotation residues containing silicon dioxide and electric furnace dust to a specified slag basicity

摘要

The Invention relates to a method for Manufacturing slag with a corresponding composition typically Synthetic Blast Furnace Slag and slag are bacisidad Cao/ SiO2 between 1.6 and a A1203 content of between 5 and 20% by weight.These procedures with Limestone and / or Waste silicate Flotation, which separates copncentrado from Limestone Lime silicateWith a SiO2 content between 25% and 50% in weight in weight by means of Powder, Baking Powder, preferably with ca0 Electric oven with a higher content of 35% by weight,A slag basicity between 1 and 1.6. The content of a12o3 is adjusted by the addition of Fly Ash and / or Bauxite, then escorificada mixture.
