13.11.2022The open stoping method and the cut and fill methods are commonly used as underground mining methods in Myanmar because most ore bodies, which are from the primary magmatic source, are located at a considerable depth from the surface. At Hermyingyi (W-Sn) Deposit Mine, the open stoping method was adopted and developed for tin-tungsten deposits.

Ore processing is a 24 hour operation. Ore is stockpiled at the processing plant, and the process begins by feeding the ore into a hopper with a loader. The ore is conveyed, and lime is added to raise its pH. Following crushing through a jaw crusher, the ore is fed into the semi autogenous grinding (SAG) mill along with water and steel balls.
