Crushing, grinding and screening technique. The purpose of grinding and regrinding is to reduce the ore to a size small enough to liberate and recover the valuable minerals. The crushing, grinding and screening systems of an IOB plant are to be designed taking into account the requirements of the downstream beneficiation processes.
Introduction to Mineral Processing 5 3.0 Liberation and Comminution 3.1 Liberation In order to separate the minerals from gangue (the waste minerals), it is necessary to crush and grind the rock to unlock, or liberate, valuable minerals so that they are partially or fully exposed.
Sample preparation of Iron ore Material Sample preparation of iron ore material involves drying, crushing, splitting, pulverizing, pelletizing or fusion. Each sample is a representative subsample of the original ore stream. Therefore, reasonable care has to be taken dur-ing splitting and processing. HERZOG iron ore laboratories are configured
Crushing and grinding are the two primary comminution processes. Crushing is normally carried out on "run-of-mine" ore, while grinding (normally carried out after crushing) may be conducted on dry or slurried material. In comminution, the size reduction of particles is done by three types of forces: compression, impact and attrition.

The first step of physical beneficiation is crushing and grinding the iron ore to its liberation size, the maximum size where individual particles of gangue are separated from the iron minerals. A flow sheet of a typical iron ore crushing and grinding circuit is shown in Figure 1.2.2 (based on Ref. [4]).This type of flow sheet is usually followed when the crude ore contains below 30% iron.
3.2.1 Crushing Equipment. Primary Crushers – Jaw and Gyratory. Within the crushing circuit, a primary crusher reduces material down to a size that can be conveyed and fed to the secondary crushing circuit. The two most common primary crushers used for coarse run-of-mine material are the jaw and gyratory crushers.

The grinding size is too large, and some ore particles and non-ore particles cannot be separated, thus preventing their flotation. If the particle size is too fine, the bubbles that rise during the flotation will push the very fine ore-containing particles away, preventing them from contacting the bubbles, thereby reducing their ability to be recovered into the concentrate.
