Mineral Beneficiation
Mineral beneficiation is a process by which valuable constituents of an ore are concentrated by means of a physical separation process. As one of the initial steps of extractive metallurgy, the main purpose is to prepare the ore prior to downstream purification processes. The most common mineral beneficiation processes include: sample preparation, comminution, size classification, and concentration.

Mineral Processing Introduction
Mineral processing is a major division in the science of Extractive Metallurgy. Extractive metallurgy has been defined as the science and art of extracting metals from their ores, refining them and preparing them for use. Within extractive metallurgy, the major divisions in the order they may most commonly occur are, Mineral Processing (or Beneficiation), Hydrometallurgy, Pyrometallurgy, and Electrometallurgy. The last steps in the winning of metals are in Physical Metallurgy where the composition and treatment of metals are varied to provide desired physical and mechanical properties.

Microwave Treatment of Ores
Microwave test work is the newest addition to Sepro Labs. Microwave treatment offers several unique benefits due to the differences in heating response between valuable minerals and waste minerals. Different minerals have different heating responses when subjected to microwave energy, and valuable minerals often heat more quickly than waste minerals. Our proprietary sorting algorithm uses this heating information to reject barren rocks prior to grinding.
