The gold mining life cycle. Step 1 (Surface) EXPLORATION. Prior to mining, exploration takes place to find gold-bearing ore in commercially viable concentrations. Geochemical and geophysical techniques are used to identify the presence of a buried ore deposit. Geologists drill to check mineral quality in identified locations.

Six steps to process iron ore. 1. Screening. We recommend that you begin by screening the iron ore to separate fine particles below the crusher's CSS before the crushing stage. A static screen is used to divert the fine particles for crushing. This step prevents overloading the crusher and increases its efficiency.
