Comminution and classification technologies of iron ore
Most of the high-grade hematite iron ores are typically subjected to simple dry processes of crushing and classification to meet the size specifications required for direct shipping ore (DSO). This involves multistages of crushing and screening to obtain lump (−31.5 + 6.3 mm) and fines (approximately −6.3 mm) products.Ore fines contain free open gold. Therefore, to estimate dissociation objectively, crushing was carried out after removing ore fines from the original sample by screening. In this case, when dividing by a cell of 12 mm, sizes of –150 + 12 and –12 mm were obtained. The size of –150 + 12 mm was sent to crusher DKD-300.Dissociation of Gold Ore from Gurbey Deposit under Impact Effects

What Is The Crushing Process MEKA
Crushing is the process of size reduction of ore. Size reduction process begins with usage of explosives at the area for production of ore. In later stages, the size reduction process performed with crushers before grinding in mills is called "crushing". Although there is no limit set, the downsizing process over 3 mm is considered as "crushingIn recent years, studies have focused mainly on the selection of appropriate parameters for ore crushing technology to achieve optimal distributions of particle sizes. The control of particle sizes in mineral processing plays a significant role in improving mineral separation efficiency.
