Lesson 4 - Ore Minerals

18問 • 1年前

問題一覧

1

natural rock or sediment that contains one or more valuable minerals, typically containing metals, that can be mined, treated, and sold at a profit.

ore

2

extracted from the earth through mining and treated or refined, often via smelting, to extract the valuable metals or minerals.

ore

3

the process of mineral extraction from rock seam or ore - a natural rock or sediment containing one or more valuable minerals.

mining

4

two methods of mining

surface mining

5

used to extract ore minerals near the surface of the Earth. The soil and rocks that cover the ores are removed through blasting.

surface mining

6

a controlled use of explosives and gas exposures to break rocks.

blasting

7

is a surface mining technique that extracts rock or minerals from the earth.

open pit mining

8

involves removing overburden, dumping it behind a desired deposit, extracting it, creating a parallel strip, and depositing waste materials onto the first strip.

strip mining

9

process of mining materials from the bottom of a body of water, including rivers, lakes, and oceans.

dredging

10

types of surface mining

open pit mining

11

used to extract the rocks, minerals, and other precious stories that can be found beneath the earth’s surface.

underground mining

12

miners need to create a tunnel to reach the ore minerals.

underground mining

13

Mineral Processing

Sampling

14

the removal of a portion which represents a whole needed for the analysis of this material.

sampling

15

important to evaluate the valuable component in an ore. This includes chemical, mineral and particle size analysis.

analysis

16

the process where the valuable components of the ore are separated through crushing and grinding. This process begins by crushing the ores to a particular size and finishes by grinding the ores into a powder form.

comminution

17

Involves the separation of the valuable minerals from the raw materials.

concentration

18

Uses the concentration to convert it to usable minerals. This involves filtration and sedimentation of the suspension and drying of the solid materials harvested from the suspension.
