Major Mines & Projects | Toromocho Mine

The Toromocho Mine is a conventional large scale open pit mine. The ore and waste rock is drilled and blasted prior to excavation by electric rope shovel excavators. The ore is loaded into ultra-class diesel powered off-highway rigid dump trucks ('' 797) and hauled to either stockpile, or dumped directly into the primary crusher.

Pebble

The pebble-bearing phyllites of the Hwanggangri Formation occur in an extensive area (Figure 4.1).Clasts constitute 3–30% of the rock by volume. Quartzite clasts are predominant, which are well rounded (Figure 4.2).Some clasts of quartzite are large (more than 2 m in diameter).Others comprise pebble-size quartzite, elongated shale, limestone, and dolomite (Figure 4.3) (Chough and Bahk, 1992).

Unit 4: The Rock Cycle

Metamorphic Rocks* There are two basic types of metamorphism: regional and local (contact). Regional metamorphism forms most of the metamorphic rock of Earth''s crust; it occurs over very large areas. Local (contact) metamorphism occurs in much smaller, more distinct areas. (Local / contact)

CHAPTER 8 (Metamorphic Rocks)

Metamorphic rocks formed under the lowest metamorphic temperatures and pressures (< 250 o C and <4 kb) can be regarded as very low-grade metamorphic rocks. Basalt metamorphosed under under these very low P-T conditions characteristically forms certain minerals called zeolites (Fig. 8.12), hence the name Zeolite Facies for this range of P-T ...
