The use of some solid minerals in the inhibition of mild steel corrosion in acidic media was investigated using the conventional weight loss and hydrogen gas evolution method. Those considered are Talc, Gypsum, Alumina, Iron chromite and Haematite. Scanning electron microscope (SEM) and Electron Dispersive X-ray spectroscopy (EDX) studies revealed the protective effectiveness of the adsorbed film of the mineral extracts on the steel surface. Results obtained indicated the minerals inhibited corrosion of the steel in the order Talc > Gypsum > Haematite > Alumina > Chromite > feldspar as the order of Inhibition efficiency. The resultant effect of solid minerals with Sida acuta plant extract is inhibitorily antagonistic due to induced corrosion rather than improve on the inhibition efficiency. Elements in the minerals got adsorped and reacted with the iron in steel to form a compound of effective protection of the metal against corrosion in its environment.
