This study attempted to conceive a possible alternative anti-corrosion agent using Mining Effluent and Silicone Mixture (ME+S) that could minimize rust contamination due to the action of the water in the air at a high relative humidity. This idea was based on the principle that mining effluents have alkaline earth solution content, which is a good deoxidizing agent because it readily combines with oxygen from rusting of metal. This experimental study also intended to use silicone to protect and prevent chemical reaction deoxidized by mining effluent to form new iron oxide. The test of iron plates with rust contamination after exposure to corroding solution were used in this study. The contamination rate of the set-up treated with ME+S and commercial anti-corrosion agents were calculated using the Standard Static Corrosion formula. The iron metal test plates were examined by counting the corrosion contamination before and after treatment periods. Five treatments and three replicates were used in the study. The Duncan’s Multiple Range Test (DMRT) and Analysis of Variance (ANOVA) were employed to determine the statistical significant differences of the results. Different concentrations of mining effluents and silicone mixtures were used namely: 25% mining effluent and 75% silicone, 50% mining effluent and 50% silicone, 75% mining effluent and 25% silicone, 100% mining effluent and 100% commercial anti-corrosion agent as soaking solutions to test iron metal test plates. Rust examination and observation of the treated iron test plates were conducted after 4 and 8 weeks period of treatments. Results showed that all treatments of ME+S and 100% mining effluent significantly reduced the corrosion rate and contamination after a treatment period of 4 and 8 weeks.
