What is an ore A naturally occurring material containing a metal in sufficient concentration to make its extraction possible What process of ore separation involves mixing crushed rock with oil, water, and detergents and agitating it

6) The difference between a high-grade ore and a low-grade ore is the: amount of a particular mineral within the ore 7) Surface mining is more common than subsurface mining because it:

Large tabular-shaped ore bodies or ore bodies lying more than 1,000 feet (300 m) below the surface are generally mined underground as well. The rock is drilled and blasted, then moved to the surface by truck, belt conveyor, or elevator. Once at the surface, the material is sent to a mill to separate the ore from the waste rock.

Earth Science Chapter 3. The process by which ore is melted to separate the useful metal from other elements. science that deals with the physical history of the earth, the rocks of which it is composed and the physical, chemical and biological changes that the earth is undergoing.

In the case of Diamond extraction from the mother rock, the process is more complicated. The entire process however utilises the properties of diamonds to separate them. Following are the basic processes by which diamonds are recovered from the ore. Crushing: Done to reduce the size of the rocks in the ore.

Iron ore is removed with dynamite and lots of heavy equipment. It starts as iron ore and is mixed with coke (carbon). This is a displacement reaction which means that the iron is separated from ...

Any type of pre-exisiting rock that has been altered by heat and pressure as a solid, is known as _____ rock Metamorphic The roots of trees and other vegetation can exert immense forces over time as the roots grow larger and intrude into small fractures.

Ore bodies are formed by a variety of geological processes. The process of ore formation is called ore genesis. Ore Preparation. It takes multiple steps to extract the "important" element from the ore: First, the ore must be separated from unwanted rocks. Then, the minerals need to be separated out of the ore

mineral processing, art of treating crude ores and mineral products in order to separate the valuable minerals from the waste rock, or gangue. It is the first process that most ores undergo after mining in order to provide a more concentrated material for the procedures of extractive metallurgy.The primary operations are comminution and concentration, but there are other important operations ...

The next step is to get the rocks which contain the mineral out of the ground. Once the ore is on the surface, the process of getting the mineral you want out of the rock can start. Once the mineral is separated from the rest of the rock, the mineral needs to be cleaned so that it can be used.

Unwanted rock and other waste materials produced when a material is removed from the earth's surface or subsurface by mining, dredging, quarrying, and excavation. Coal A solid fossil fuel that is formed in several stages as the buried remains of land plants that lived 300-400 million years.

The ore is a chemical compound of that metal and the process of smelting the ore involvesf breaking the compound up using heat and "reducing it" essentially removing oxygen - …

Open-pit – 90% of ore is mined using the open pit method. Ores near the surface can be quarried after removal of the surface layers. The ore An ore is a rock that contains enough metal to make it worthwhile extracting. Grinding The ore is crushed, then ground into powder. Concentrating The ore is enriched using a process called froth flotation.

Crushing, a form of comminution, one of the unit operations of mineral processing. In the field of extractive metallurgy, mineral processing, also known as ore dressing, is the process of separating commercially valuable minerals from their ores .
