One way to solve this problem is the use of alternative sand bulk materials . As the latter, it is proposed to use abrasive materials having magnetic properties [15-18], for example, magnetite (FeFe2O4), which is the iron oxide of natural origin, and iron scale (FeOFe2O3), which is a by-product of foundry and forging. These materials are similar to quartz sand in terms of hardness.
In this regard, the study of the use of magnetite and iron scale in order to increase the coefficient of
