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.

The rock cycle is the natural, continuous process that forms, breaks down, and reforms rock through geological, chemical, and physical processes. Through the cycle, rocks convert between igneous, metamorphic, and sedimentary forms. It is a dynamic system that recycles Earth's materials in different forms, from molten magma deep below …

The basic extraction of metals from ores has the following steps. Grinding and Crushing. The bigger chunks of the ore extracted are crushed and ground in ball mills and crushers. It helps to increase the surface area of the chunks for better chemical actions later. In technical terms, it is called pulverisation.
