type of ore process

ore National Geographic Society

This type of ore genesis is called a surficial process. Ore can also fall to Earth as rocky debris from elsewhere in the solar system. These pieces of debris, entering the atmosphere as shooting stars, are called meteorites. Many meteorites contain large amounts of iron ore. Ore is a nonrenewable resource.

Ore forming processes ~ Learning Geology

Hydrothermal process is the most common ore forming process. Water is heated by the magma chamber and this water dissolves metals. Metals are dissolved in the water and this solution seeps through cracks, fractures and through permeable rocks until they are precipitated and form a deposit. There are three types of water sources

type of ore process

Types of Ore. Ore is rock that contains economic amounts of a particular element eg gold ore iron ore molybdenum ore or praseodimium ore In contrast rock that is not judged to contain economic quantities of an element is categorized as waste rock The metals in ore can occur in many different minerals compounds in the rock As an example copper occurs in more than 50 minerals

Ore Deposit an overview ScienceDirect Topics

A mass transfer process in the form of magmatism is the first step leading to the potential formation of magmatic ore deposits. Another important perspective is that ore minerals such as sulfide and oxide phases do not generally form in amounts large enough for mining when mantle-derived magmas solidify and freeze in volcanic environments.

Mineral Ore Deposits: Meaning, Origin and Types Geology

An ore deposit may be either of igneous or of sedimentary origin. Some deposits are related to metamorphic processes and are as such classified as deposits of metamorphic origin. Within these three broad modes of origin, a mineral deposit of economic value might have originated due to set of simple or complex processes. Types of Ore Deposits: 1.

Mar 09, 2018· Depending on the type of ore body, the appropriate variation is selected. Shrinkage Stoping. Shrinkage stoping is an overhand mining method that is used for self-supporting vertical ore bodies. In this method, ore is mined in horizontal slices, starting from the bottom to the top of the stope.

Concentration of Ore Definition, Types and Properties of Ore

The powdered ore is dissolved in a chemical, usually a strong solution of NaOH. The chemical solution dissolves the metal in the ore and it can be extracted and separated from the gangue by extracting the chemical solution. Extraction of the Aluminium metal from Bauxite ore is done using this process.

How Gold Is Mined Gold Mining Process World Gold Council

The lifecycle of a gold mine. People in hard hats working underground is what often comes to mind when thinking about how gold is mined. Yet mining the ore is just one stage in a long and complex gold mining process. Long before any gold can be extracted, significant exploration and development needs to take place, both to determine, as accurately as possible, the size of the deposit as well
