Cut

2016/7/13Under the CIM Standards on Mineral Resources and Reserves - Definitions and Guidelines, a mineral resource must be in "such form, grade or quality and quantity that there are reasonable prospects for eventual economic extraction". The implications of this for the selection of a cut-off grade are discussed in this article by Micon's V.P. Geology, Terry Hennessey. Get price

Minerals

A large number of unexploited low-grade vanadium-titanium magnetite deposits have been found in the Chao-yang area of China in recent years. The reserves are estimated at more than 20 billion tons. A mineralogical study of raw sample indicated that it was a typical low-grade vanadium-titanium magnetite ore with weathering. Most of vanadium-titanium magnetite was replaced by martite and sphene Get price

Ore Grade Control in Mining: XRF: Test your ore the right

Handheld XRF can increase profitability in ore control as well as almost every phase of mining operations. Whether you are conducting open pit or underground grade control, with portable handheld XRF analyzers, your job is made easier. Narrowing the gap between planned production and actual production has long been a focus of mining operations. Preventing ore from ending up as waste is a Get price

Ore

Ore Ore is metalliferous rock that can be mined and processed at a profit. Although a broader definition includes nonmetallic rocks like rock salt and gypsum, most geologists classify these materials as industrial rocks and minerals.History Gold, silver, and copper artifacts left by prehistoric tribes and ancient civilizations attest to an interest in ores extending back to earliest times.

What is the Relationship between Head Grade and

Some plant operators claim their metallurgical recovery targets are harder, more difficult, to meet as head grades drops down. Is it true or is it just voodoo? Using Mineralogy can answer this question scientifically. Relationship between Head Grade and Mineral Liberation EXAMPLE The red/white dot points to the actual monthly liberation of 42% VS history. The poorly monthly results can be Get price

VEIN DEPOSITS

A great many valuable ore minerals, such as native gold or silver or metal sulphides, are deposited along with gangue minerals, mainly quartz and/or calcite, in a vein structure. A vein system is a group of discrete veins with similar characteristics and usually related to the same structure. Get price

Ore Mineral

Iron ore minerals, particularly hematite and goethite, are beneficiated by a combination of size fraction, preconcentration, and flotation in stages (Fig. 13.45).Iron ore requires removal of silicate impurities of a finer size by flotation for higher-grade products of +60% Fe. Get price

Orebody types

Even where ore itself is readily identified, the valuable minerals are often not visible. The grade of ore is the concentration of valuable mineral(s) in the ore, usually expressed as a percentage (for example, %Cu) but sometimes in grammes per tonne (g/t) such as in the case of gold and platinum group metals.

Mineral

A mineral is, broadly speaking, a solid chemical compound that occurs naturally in pure form. Minerals are most commonly associated with rocks due to the presence of minerals within rocks. These rocks may consist of one type of mineral, or may be an aggregate of two or more different types of minerals, spacially segregated into distinct phases. Get price
