The purpose of silver ore beneficiation is to upgrade the ore and achieve its economic value. A process adopted to upgrade silver ore content is called beneficiation. The capital investment and operation costs of milling equipment and separating machine are high. For this reason, economics plays a large part in determining the method of silver ore beneficiation equipment.
silver ore beneficiation process
Generally speaking, silver ore beneficiation process can be divided into the following steps, namely, communication, grading, separating, concentrating and drying.
Crushing process: silver ore beneficiation begins with the milling of extracted ore in preparation for further activities to recover silver values. Milling operations are designed to produce uniform size particles by crushing, grinding, and wet or dry classification. Milling is a multistaged process and it can be divided into primary crushing, secondary crushing and fine crushing. Primary crushing and screening take place at the mine site. Primary crushing is accomplished by using jaw crushers and impact crushers. Oversize material is passed through additional crushers and classifiers to achieve the desired particle size.
The ore is then crushed and sized at a secondary milling facility. Secondary crushing, if necessary and economical, is accomplished by using standard cone crushers followed by short head cone crushers.
The subsequent crushing is called fine crushing, and it can be achieved by using various kinds of grinding mills. For example, you can choose ball mill, super thin grinding mill, vertical grinding mill and so on.
Magnetic separation: magnetic separation is most commonly used to separate natural magnetic ore from a variety of less-magnetic or nonmagnetic material. After washing and grading, silver ore particles were fed into the magnetic separation. Due to the different susceptibility of various minerals, magnetic and mechanical force can separate the magnetic material from the mixture materials.
After being separated, the silver ore particles were taken into thickener for concentrating. Thickening reduces the water content of the concentrate slurry, separating the water from the heavier mineral-rich solids through gravity. Then, after drying, you can get dry materials.
silver ore beneficiation equipment
The commonly used silver ore beneficiation equipment mainly including crushing equipment, grinding equipment, separating equipment equipment.
In terms of crushing and grinding equipment, you have the following choices: jaw crusher, impact crusher, cone crusher, ball mill, vertical roller mill, trapezium mill, super thin grinding mill and so on. Each type of the crusher and grinder has different models, so you can choose the suitable one according to your actual situation.
