Secondary Crushers – Cone Crusher. The most common type of secondary crusher is the cone …
Cone crushers. Cone crushers are one of the main choices for secondary crushing. A cone crusher is a powerful machine that is used in large-scale industries for crushing various types of materials into smaller sizes. It works by applying pressure onto the material and squeezing it against a rotating mantle to create compression and force.

Pyrolusite is a mineral essentially containing manganese dioxide (MnO₂) Romanechite and pyrolusite are the most important manganese minerals. The mineral is obtained by reduction of the oxide with magnesium, sodium, aluminum, and electrolysis. Pyrolusite is widely used in the manufacture of various manganese-bronze alloys.
First Online: 13 July 2023. 41 Accesses. Abstract. This chapter describes the important manganese ore Pyrolusite (abbrv. prl ), as seen with optical, reflected light microscopy.
The major innovations with respect to conventional wisdom is the avoidance of soda ash, fluorspar and pyrolusite, and the use of fused borax (anhydrous boric acid B203, also known as borax glass) rather than borax (sodium tetraborate Na2B407.10H20).
The manganese-extraction curves as a function of volume of solution applied to the column are shown in figure 1 for the seven silver-bearing samples. The manganese in all the samples except NV-1 was predominately psilomelane and pyrolusite; therefore, it readily leached to the 80- to 95-pct extraction level.
