Comminution circuits for gold ore processing
Unlike ball-mill circuits, it can be very difficult operationally to trade grind for throughput in a SAG circuit. Once designed and constructed for a given ore type, a SAG mill circuit has only limited flexibility to deliver varying product sizes. This is particularly true for those SAG circuits designed with a coarse closing size.

Zinc Ore is a mineral block found underground. It can be processed into Zinc Ingots. Zinc ore must be mined with an iron pickaxe or higher, or else it drops nothing. Zinc ore drops 1 Raw Zinc unless the player uses Silk Touch or Fortune. Zinc Ore can generate in the Overworld in the form of Blobs. It can be found between Y levels -63 to 70.

Open-Circuit Technology of Zinc Oxide Ore Flotation with …
The primary source for zinc extraction is zinc sulfide ore; however, the continuous increase in global demand for zinc resources has resulted in the gradual depletion of zinc sulfide ore resources. Therefore, the possibility of using zinc oxide ores must be investigated to satisfy the increasing demand [3,4,5].

Comminution circuits for gold ore processing
The PTFI mills treat ore from the Grasberg (open pit) and Deep Ore Zone (underground) deposits, and recover gold contained in copper concentrate via flotation and gravity circuits. Since SAG ball-mill circuits represent the single largest type of gold milling comminution circuits, such circuits will be the focus of this chapter.
