Small-Scale Tests to Characterise Ore Grindibility

The Bond ball mill grindability test is performed according to the original Bond procedure [4]. It requires 10kg of minus 6-mesh (3.35mm) material that is preferably prepared at the testing facility, by stagecrushing the sample to 100% passing 6-mesh, but normally less than 5kg are actually used in the test. The test is closed with a fine screen (typically in the range 65 mesh to 270 mesh ...

Standard Grindability Tests and Calculations

standard grindability test su-pplies a rela- tively accurate method for predicting grinding results. Table I gives the condensed results of 374 standard ball-mill grindability tests. Those for each mesh size are arranged in the order of increasing ease of grinding, so that the list for any mesh constitutes an as- cending graduated scale of grindabilities. The grindabilities of ores on which ...

Beryllium Exposure Testing - ORISE

A complex medical test, the BeLPT is the primary diagnostic test to determine if workers exposed to beryllium have become sensitized to it. The sensitization can be an indicator of chronic beryllium disease (CBD), a treatable but incurable disease. Workers may have been exposed to beryllium as it is a metal and alloy used in various manufacturing processes.

Beryllium Testing Department of Energy

Medical screening for beryllium sensitization and CBD usually begins with a Beryllium Lymphocyte Proliferation Test (BeLPT). The BeLPT is a laboratory blood test that examines how a type of disease-fighting blood cells that are normally found in the body, called lymphocytes, reacts to beryllium. In general terms, the BeLPT is performed by culturing lymphocytes from peripheral blood. If these ...

Beryllium - Biolab

The best test for beryllium sensitivity is the MELISA stimulation index. The reference interval for whole blood Be is ≤ 30 nmol/L. The reference interval for urine Be is ≤ 7.8 umol/mol creatinine. There is no established statutory maximum permitted level for Be in drinking water. Results for the in vitro lymphocyte transformation test (MELISA) are expressed as a stimulation index for ...
