Examples of Metamorphic Changes in Rocks | Geology

Under conditions of dynamic metamorphism, granites are simply broken and crushed forming a newly structured rock called crush breccia. In other cases, the hard minerals of granite like quartz and felspars may be flattened and elongated under the imposed loads so that ultimately they remain embedded in the finely crushed ground mass produced due to crushing of other minerals of granite.

12.11 Secondary Lead Processing 12.11.1 General Secondary lead smelters produce lead and lead alloys from lead-bearing scrap material. More than 60 percent of all secondary lead is derived from scrap automobile batteries. Each battery contains approximately 8.2 kg (18 lb) of lead, consisting of 40 percent lead alloys and 60 percent lead oxide.

Copper Ore Processing Methods

Copper Ore Processing Methods. The four major steps in the production of marketable copper are mining, concentrating, smelting, and refining. In a few instances, however, leaching takes the place of concentrating, smelting, and refining. At present, although considerable leaching and direct-smelting ores are produced, the bulk of the copper ore ...

Mechanical Weathering Through Physical Processes

Mechanical weathering is the set of weathering processes that break apart rocks into particles (sediment) through physical processes. The most common form of mechanical weathering is the freeze-thaw cycle. Water seeps into holes and cracks in rocks. The water freezes and expands, making the holes larger. Then more water seeps in and freezes.
