How can one identify platinum ore?
Platinum ore can be identified by its silver-white color, high density, and resistance to corrosion. It is often found in association with other minerals such as pyrite and chromite. Additionally, platinum ore may exhibit a metallic luster and can be identified through chemical tests such as acid dissolution or fire assay.
What is the relationship between mineral ore and gangue?
Mineral ore is the valuable material that can be extracted and processed for its useful properties, while gangue is the unwanted material that is typically separated from the ore during the extraction process. Gangue does not have any economic value and is usually discarded as waste material. The relationship between mineral ore and gangue is that they are often found together in the same rock or ore deposit, with the goal of separating the valuable ore from the gangue to extract the desired minerals.
What is metallic ore and non metallic ore?
Metallic ores are those that contain metal elements, such as iron ore or gold ore, which can be extracted and processed to obtain the metal. Non-metallic ores are those that do not contain metal elements but may still have value, such as sand, gravel, or limestone, which are used in construction and manufacturing industries.
What type of ore is oil?
Oil is not classified as an ore. Ores are naturally occurring rocks that contain minerals or metals that can be extracted and processed for economic value, whereas oil is a fossil fuel that is extracted from underground reservoirs and used primarily for energy production.
.what is the loose bulk density of iron ore?
The solid density of iron ore generally lies between 3.35 and 5.6 tonnes per cubic metre, depending on the particular characteristics of the ore being considered. When the ore is broken up, air spaces are formed between the particles of ore, and the "apparent" density will be lower. The loose bulk density is one measure, the compacted bulk density is another, and the fluidised bulk density is yet another. The loose bulk density is measured on a sample of loose ore, that has not been allowed to self-compact over time, and has not been mechanically compacted. It will generally measure between 50% and 60% of the value of the solid density.
What is it called when you analyze ore?
assay
How do you tell high grade gold ore from low grade gold ore by visual inspection?
cannot be done, requires an assay.
What is an assay ton?
An assay ton is a standard quantity used in assaying, the act of ascertaining the proportion of a particular metal in an ore or alloy, typically equal to 29.16 grams (short assay ton) or 32.6 grams (long assay ton).
How do you convert assay value from dried basis to as is bysis?
xx.x% on a dried basis implies that the material will have had all possible liquid impurities (water, solvents, residual liquid chemicals) removed by the drying process.Let's call w% is % of (water content, solvents, and residual) all combine. Your as-is value would be:xx.x% * (100 - w%)% as-is = ---------------------100Hopes that help.
Can you put the word assay in a sentence?
The old miners in gold rush country took their nuggets to the local Assay Office, to determine -- to assay -- the value of the metal in their nuggets.
USA value of sverige ore?
The dollar value for the us dollar and sverige ore is 30 ore to 1 dollar.
How does one determine the value of gold or silver ore?
The ore must be assayed.
What is the sverige ore 50 worth?

What is the value of g and G?
Ore -G
Why do economic factors play a part in determining what an ore is?
Because it depends on what type of ore it is. If it is a certain type of ore, then there is a certain amount of value in money for it. That's Why.
Fiducial Limits in Microbiological Assay?
fiducial limits are similar to confidence limits. They contain the parameter of interest. But i m also not sure of the difference between the 2 limits. And the interpretation is same wether it's microbio or chem or bio.
