ABSTRACT:
The invention relates to a method for blast cleaning using ilmenite tailings particles between 10 mesh and 250 mesh as impact abrasive material. Ilmenite tailing particles are a waste product obtained in a beneficiation plant of an ilmenite ore (FeTiO3) metallurgical complex. The particles are preferably washed, dried, and screened before being used as impact abrasive material. They are separated in particle-size range to improve their efficiency for blast cleaning.
