Sampling for Assaying

Sampling is the most important procedure in arriving at the value of an ore. Improper sampling makes other procedures, including assaying, valueless, as the sample must truly represent the ore from which it is taken. Before sampling, clean fresh faces must be exposed in order to prevent the possibility of salting. Having taken a large representative sample by chiseling 3″ to 6″ wide and 1

Sample Preparation and Assaying of Coarse Gold Ores AusIMM

A study was conducted to evaluate the effectiveness of the three types of sample grinders routinely used in the mining industry for the sample preparation of gold ores with particular emphasis placed on testing their capacity to produce a representative assay sample of coarse gold ores. The grinders used in this study are the Labtechnics...

Mineral Sample Preparation

Mineral Sample Preparation. Mineral Sample Preparation is a vital stage in the process of minerals analytical testing. The purpose of sample preparation is generally the production of a homogeneous sub-sample, representative of the material submitted to the laboratory. Correct preparation is critical to obtaining meaningful analytical results.

12 LABORATORY SAMPLE PREPARATION

12.2 General Guidance for Sample Preparation . Some general considerations during sample preparation are to minimize sample losses and to prevent contamination. Possible mechanisms for sample loss during preparation steps are discussed in Section 12.2.1, and the contamination of samples from sources in the laboratory is discussed in Section 12.2.2.

Assaying Ores to determine gold content

If the sample does not reflect the average nature of the material, no amount of technical accuracy in processing the sample will provide a correct result. The first step in any assay is sample preparation (I have a separate web page on methods for crushing and pulverizing rock samples and specimens).

Send samples to: CSAL INC. 1050 Spire Dr Unit I Prescott, AZ 86305 Samples should be individually labeled, sealed and protected for shipping. We require 227 grams (1/2 lb) to 454 grams (1 lb) of ore material for analysis and at least 30 grams for concentrates. Any sample greater than 2068 gram (5 lbs), additional fees may apply per sample.

Sampling of run-of-mine mill feed— A practical approach

A sample tree experiment involves splitting at different top sizes, followed by comminution and assaying5. Figure 1 shows the sample tree flowsheet. Two ores were evaluated via this sampling technique. The first sample was a low-grade gold ore (about 5 g/t gold) mill feed sample from a South African gold mine. The particle size was 95% -12 mm.

Sample preparation and analytical methods

Sample preparation and ores (e.g. Au and PGE’s) where the number of mineral If the representatitivity of the sample is lost during sample preparation, the subsequent assaying cannot correct the damage done. Sample preparation methods should therefore be selected as carefully as the actual analytical methods.

ELISA Sample preparation and collection ELISA Genie

Collect the serum fraction and assay promptly or aliquot and store the samples at -80°C. Avoid multiple freeze-thaw cycles. If serum separator tubes are not being used, allow samples to clot overnight at 2-8°C. Centrifuge for 10 minutes at 1,000x g. Remove serum and assay promptly or aliquot and store the samples at -80°C.
