ORES

通報

問題一覧

A rock or mineral is considered an ore based on:

overall chemical composition, percentage of extractable resource with respect to its total volume

Determined by the LOCATION, CONCENTRATION, DEPTH, SCOPE and TECHNOLOGIES used to extract and process an ore

Profitability

Locating Ores are located by recognizing that geologic processes can produce localized enrichment of one or more minerals and it only occurs in certain environment

Potential ore (buddies)

Most common type of ore mineral

Hydrothermal Fluid Circulation

Form when GROUND SALT IS HEATED by magma or when aqueous solutions are expelled from a cooling platonic body

Hydrothermal Fluid Circulation

Special type of magma that originates deep within and source of diamond (only crystallize at depths >150km)

Kimberlite Magma

Form EVAPORITE DEPOSITS from the PRECIPITATION OF SALTWATER mineral and evaporation of lake water

Chemical Sedimentary Processes

Results of rocks EXPOSED TO OXYGEN AND WATER under-going chemical weathering Common in tropical areas

Residual Ore Deposits

A set of processes used to extract useful resources from non-renewable sources An intensive and sophisticated process

Mining Ores

Looking for the ore body (deposit that can yield large amount of require ore minimum)

Prospecting or Exploration

Extracting a part of the ore to determine the RESULTING CORE, quality, and amount of ore minimum (grade)

Drilling

Determining size, shape, and grade distribution throughout the deposit

Modelling

Considering SOCIAL AND ENVIRONMENT ASPECTS, financing ways of managing consequences with the purpose of bringing the area back as similar as past

Identifying and Assessing the Potential Impacts

Creating appropriate mine and OPERATIONAL DESIGN and proceeding once requirements are done

Designing and Constructing the mine

Separating high grade ores

Ore Extraction

Crushing and contraction Waste materials are release

Milling

Closure and depleted mine Site is cleaned and reclaimed/rehabilitated

Mine site Decomissions

EXTRACTION METHODS Very little waste rock is LEFT BEHIND AFTER MILLING Type of deposits aren’t economically viable

Sand and Gravel Extraction

ECTRACTION METHOD Huge QUANTITY OF ROCK IS OFTEN REMOVED/discarded so a relatively small amount of ore can be recovered

Extraction from buried ore bodies

EXTRACTION METHODS Produced from ores through cruising, separating, and PURIFYING

Ore Processing

Because of location, the PH is the — most mineralized country in the world (3 in gold, 4 in copper, 5th in nickel)

5th

Approximately — metric tons of metallic and — metric tons of nonmetallic mineral resetses 30 m hectares or about 9M hectare

14.5B 68B

The most prolific copper and gold (until yesterday) products in the PH are found in —

Baguio and Mankayan

Types of Mineral Resources

Metallic Mineral Deposits Non-metallic Mineral Deposits

: the Earth’s crust is broken into a dozen or more plates of different sizes that move relative to one another (lithosphere)

Plate Tectonics

These plates are moving slowly on top of a hot and more mobile material called the

Asthenosphere

Ore Deposits

MHS — PR Magmatic ore deposits Hydrothermal ore deposits Sedimentary ore deposits Place ore deposits Residual ore deposits

Crystal Settling As magma cools down, heavier minerals tend to — early and settle at the lower portion of the magma chamber

crystallize

From a basaltic magma, chromite (FeCr2O4), magnetite (Fe3O4), and Platinum (Pt) can be concentrated through —

crystal settling

: hot, residual watery fluids derived during the later stages of magma crystallization and may contain large amount of dissolved metals
