Measuring the hardness of

For design purposes, you need an estimation or prediction of your SAG Mill's tonnage; well, there are 3 ways to generate good rock "ore" hardness testing data for SAG and ball mill circuit grindability from half drill core. We can abbreviate the discussion by saying there are three "religions" of grinding, and there are small-scale tests suitable for all three of the major …

Scraping it across a streak plate is a convenient way to conduct this test. Hints to other mineral properties can be obtained while doing the streak test. Minerals harder than the streak plate are quickly identified. Experienced testers can estimate the hardness of a specimen by how difficult it is to mark the streak plate.

Quick Test Method for Determining Specific ...

Measure: Select the Hardness test. Hardness is a measure of how easily a mineral can be scratched. It is measured on a scale of 1 to 10 called Mohs scale. If a mineral scratches a fingernail (hardness 2.5) but not a penny (3.5), its hardness is about 3. A. Drag the mineral sample across each test object. Which objects are scratched? B.

Carbonate Minerals

ordered list of minerals' hardness. How does it work? Steps for testing the hardness of a mineral: 1. Select a fresh surface of the unknown mineral. 2. Hold the mineral and scratch it with an object/ mineral of known hardness, e.g. fingernail (H = 2.5) or quartz (H = 7) (or whatever is most convenient — its hardness must be known though). 3.

Streak Test for Minerals

Jul 21, 2020· Then, look at the Mohs hardness scale to identify minerals that have the same hardness level. For example, if the copper penny (3) didn't scratch the mineral but a steel nail (5.5) did, you know that the hardness is between these. You can safely estimate the hardness of your mineral to be 4, which might be fluorite.

A simplified and crude test for hardness is to test whether or not a sharp corner or edge of a sample scratches (or indents) a glass plate. A numerical reference scale for hardness was devised by Mohs. A glass plate has a hardness of about 5 1/2 on the Mohs hardness scale. More information on hardness in mineral identification

Testing the hardness of rocks is less effective than testing the hardness of minerals. A rock is basically a mixture of various minerals, although it can contain non-mineral materials such as natural glass and fossils. (Fossils aren't minerals because they are organic, while glass isn't a mineral because it lacks an internal crystalline structure).
