- 2. Introduction of Mining ● Mining is the extraction of valuable minerals or other geological materials from the earth, usually from an ore body, vein or (coal) seam. ● Any material that cannot be grown through agricultural processes, or created artificially in a laboratory or factory, is usually mined. Mining in a wider sense include extraction of non-renewable resource

- 17. Bronze Age It is known that bronze age man valued copper and bronze as both artistic and practical objects. The ore was gained by using only simple stone and bone tools. It is thought that initially raw metallic copper found on the surface would have attracted the ancients to the uses of copper. History of Mining

- 19. Iron Age Iron age generally is considering to have started about 1200 B.C. Existing iron ore deposits were not exploited in ancient Egypt until the Late Period, but the metal was occasionally found in its meteoric form and put to use as early as the 4th millennium BCE. History of Mining

- 21. The smelting of iron was by the process known as the 'Bloomery' method. Bellows were used to fan the flames and the end product was a malleable ball of impure iron which could be hammered to shape. History of Mining Iron Age

- 33. What is Prospecting ? The process of looking for mineral deposits.
- 34. Types of Prospecting ● Traditional Prospecting ● Modern Prospecting
- 35. Types of Prospecting Traditional Prospecting Its prospectors was looking for simple, easy to find mineralization-native gold in stream gravels or in veins out cropping on the rocky sides of the mountains The old-time prospector used a burro or mule to carry his camping supplies, pick and shovel a pan for washing stream gravels
- 36. Figure 20. Burro or Mule
- 37. Modern Prospecting The modern prospector is a member of a team of highly trained specialists who use sophisticated equipment in a planned, systematic search. The team generally include experts in geology, geophysics, geochemistry, computer techniques, drilling, mineral economics, metallurgy, and related fields. Types of Prospecting

- 40. Prospecting Geological guides in prospecting Metallogenic associations -It deals with the location where undiscovered mineral deposit relative of know regional trends of related deposits.
- 41. Natural associations The relation of ore deposited structural features such as faults, brecciate and conformities and the boarders of intrusions is used as a guide in prospecting Prospecting Geological guides in prospecting
- 42. Zoning Most closely followed guides to ore is the expected pattern of mineral zoning. Ore and gangue minerals change in character with distance from the center of mineralization. Prospecting Geological guides in prospecting
- 43. Outcrops Gossans, the residue of red, brown, and yellow iron oxides and silica that remains from the weathering is used in prospecting as a guide to hidden primary mineralization. Prospecting Geological guides in prospecting
- 46. Prospecting Prospecting methods Direct method Geochemical method Biochemical method Geobotanical method Remote sensing
- 47. Direct method the topography itself may give evidence of abrupt depressions related to the leaching and collapse of sulfide ore minerals. Prospecting Prospecting methods
- 48. Prospecting Prospecting methods Geochemical methods- involve the field and laboratory analysis of sampled rock, soil, vegetation and other natural materials for trace amounts of the principal indicator elements of an ore body.
- 49. Prospecting Prospecting methods Biochemical prospecting this method is essentially an indirect means of collecting information from soil and groundwater. Roots of trees and bushes accumulate certain elements From the subsurface and transmit them to foliage.
- 50. Prospecting Prospecting methods Geobotanical prospecting this is a method in which a presence of morphological or mutational changes vegetation is taken as a guide to local geochemical condition.
- 51. Electrical Survey It uses the electrical properties of rock to locate any mineral in the area Prospecting Prospecting methods
- 53. It is used for by prospectors for close look and to study the rocks. Equipments Use in Prospecting Magnifier
- 54. Suction Tweezer Equipments Use in Prospecting For easy extraction of tiny gold.
- 55. Equipments Use in Prospecting Prospector’s Hammer For hammering chisels, etc
- 56. Equipments Use in Prospecting Shovel For digging
- 57. Equipments Use in Prospecting Bulb Snifter Extracting gold from pans.
- 58. Equipments Use in Prospecting Chisels Splitting rocks.
- 59. Equipments Use in Prospecting Pick Mattocks For digging hard rocks..
- 60. Equipments Use in Prospecting Magnetic Compass The oldest magnetic prospecting instrument, which measures the field direction.
- 61. Exploration
- 62. What is Exploration? Exploration is the process of closely examining a deposits to determined it’s size, shape, mineral content and other characteristics.
- 63. Exploration Exploration techniques Geological Inference This is the primary method in the initial stage of exploration, it is critical in interpreting the results of other methods. The prospecting team starts with geologic map of the region. Such map shows the various kinds of rocks at the surface and for thousands of feet underground as well the structural features of the rocks thickness of beds, folds, faults, fractures, and intrusions.
- 65. Geophysical method involve the measuring slight differences in physical properties of rocks and minerals. Exploration Exploration techniques
- 68. Exploration equipments Gravimeters Use in gravity method which typically consist of a weigh attached to a string that stretches or contracts corresponding to an increase or decrease in gravity.

- 70. Exploration equipments Scintillometers Scintillometers is a device used to measure small fluctuations of the refractive index of air caused by variations in temperature, humidity and pressure.

- 72. Exploration equipments Seismograph Use to measure earthquake. The goal of the seismograph is to accurately record the motion of the ground during a quake.
