Metallefrous Mining (5,8,9) Flashcards
What are metalliferous ores?
A rock that can be worked ecomonically for a metal that it contains. The contain high concentrations of the ores
What are native ores?
an ore that contains a metal in its elemental free state
What is the current price of gold
£29.43 per gram
What are sulphide ores?
An ore that contanis a metal or a groupd of metals in combination with sulphur
What are oxide ores?
a ore that contains a mental in combination with oxyden
What are carbonate and sulpate ores?
an ore that contains a metal in combinatio with sulpur or carbone
What are magmatic ore despoits
These are the biggest source of platiminum, formed through crystal settling within magma chambers
What is the bushveld complex
Locate in south africa, a large ignoues intrusion with 75% of the worlds PGE
What are contact metamorphic ores?
Magma gives of irons with react and replace the minerals in the surounding rocks.
What are hydrothermal ore despoits?
form through hot waters transporting rare metals through the crust on which cooling precipitate out both ore
What are sedimentary ore depoits?
When rocks are weather some of their compoments are carried away in solution and then deposited else where, most of the worlds iron comes from here
Ores in metroimpacts
Found in ontario in the US
So what are the main types of ore deposits?
Magmatic Hydrothermal Sedimentary Weathering Impacts
What effects how economic an ore is?
It depens on its ratio to the ore,
What is the cycle of metal mining ores
Exploration Evaluation Product mining Raw materials Products Modern Society
What is scoping?
Its the scope is the whole management plan for the project
Stage 1
Invesntment, Reconnaissance and geographical information
What is a method of remote sensing
Microwave radar
Stage 2

ground mapping
geophysics
What is stream sampling
Steam sediments in diamond exploration can be used to work out if there are more in the rock
Stage 3
Mineral rescource evaluation using cores to work out if there mineral is worth mining and desinging a mine
Stage 4
Infrastucte and mining, the mining operatations them selves
Stage 5
Mineral processing, this is usoing the minerals found to turn into products
What are the processes
Crushing
Ore seperations
Concentraions
Smelting
Stage 6
Closure of the mine and remediation
