Overview of Metal Ores and Slags Services
At Conti Testing, we provide comprehensive analytical chemistry services for copper, nickel, aluminum, and ferrous metal slags, as well as processing inputs like alloys and fluxes used in galvanization and other coatings, pickling liquor, mold powders, lubricants, and refractory materials. Further, we conduct in-depth chemical analysis and composition verification for ores including iron (hematite, magnetite, titanomagnetite), alumina (bauxite), copper (bornite, covellite, chalcocite), and nickel (nickeline). With advanced techniques such as ICP-OES, ICP-MS, and XRD, as well as traditional wet chemistry, our mineral and metallurgical testing lab ensures precise results for quality control, environmental compliance, and process optimization.
