Recursos Minerais

Recursos minerais metálicos

• Metallic mineral resources are deposits of metals such as iron, copper, gold, and silver that can be extracted and used for various industrial and commercial purposes.
• Examples of metallic mineral resources include:
  • Iron ore
  • Copper ore
  • Gold ore
  • Silver ore

Clarke

• Clarke is a measure of the average concentration of a mineral resource in the Earth's crust.
• It is used to estimate the abundance of a mineral resource and to determine its economic viability.

Jazigo mineral

• A jazigo mineral is a mineral deposit that has a high concentration of minerals and can be economically extracted.
• Jazigos can be classified into different types, including:
  • Magmatic jazigos (formed from magma)
  • Hydrothermal jazigos (formed from hot water)
  • Sedimentary jazigos (formed from sedimentation)

Ganga ou estéril

• Ganga or estéril refers to the waste rock or minerals that are extracted along with the desired mineral resource.
• Ganga is typically removed and separated from the valuable minerals during the mining process.

Escombreiras

• Escombreiras are waste rock dumps or piles that are created during the mining process.
• They can be a source of environmental pollution and can pose a risk to local ecosystems.

Recursos minerais não metálicos

• Non-metallic mineral resources are deposits of minerals that are not metals, such as:
  • Sand
  • Gravel
  • Limestone
  • Clays
  • Silica

Impactes da utilização dos recursos minerais

• The use of mineral resources can have significant environmental and social impacts, including:
  • Deforestation and habitat destruction
  • Water pollution
  • Soil erosion
  • Displacement of communities
  • Health risks to miners and local populations

Problemas ambientais da atividade mineira

• Environmental problems associated with mining activities include:
  • Air and water pollution
  • Soil contamination
  • Land degradation
  • Loss of biodiversity
  • Climate change
• These problems can be mitigated through sustainable mining practices, rehabilitation of mined areas, and strict environmental regulations.
