These data are shown in table 2. The median size of the longest axis of alteration surrounding a porphyry copper deposit is 4–5 km, while the median size area of alteration is 7–8 km2 (table 2). Vertical Extent The vertical extent of ore is dependent upon the lower copper cutoff grade, which will vary with the price of copper …
3.8 Gross Sample — Sample as collected from a sub-lot, that is, the quantity of ore consisting of one or several increments or unit samples taken from a sub-lot. 3.9 Size Sample — The sample taken for the determination of the size distribution of the lot or sub-lot. 3.10 Laboratory Sample (Sub-lot) — The quantity of ore obtained by ...
Aug 02, 2014 The values of d are the diameter of the largest particle of ore to be sampled. I have found that it can be useful in sampling, when used by pesonnel that understand the ore, and sampling, The table, above, relates the particle size of the material being sampled to the sample size required for a representative sample.
Jun 29, 2020 For common page sizes and font sizes, somehow 30 appeared to be this limit and became so popular that “above 30 it is Normal” was repeated enough to become part of the folklore. Caveat: for random samples, sample mean is approximately t distributed with degrees of freedom. This means sample size should be at least 31.
Lot size – It is the entire set of items/observations from where samples are drawn.; Sample size – It is the number of items that are drawn randomly from a lot for inspection.; Acceptance number – It is the maximum number of defects or defectives that are allowed in an acceptable lot.; Acceptable Quality Level (AQL) – It is the highest proportion of defectives in a lot or batch that is ...

Copper ores. An ore is a rock containing enough valuable mineral to make it worth extracting. In the case of copper, it is worth extracting when there is about 2 kg of copper per 1,000 kg of ore (0.2%). Copper minerals are found in over one hundred varieties, although only a few have been worked for copper on a large scale.
The copper anodes are then refined electrolytically to 99.9% purity. Copper melted under non oxidizing conditions is called oxygen free copper. The most popular form of pure copper is the standard electrical wire grade of copper (C11000) contains 99.95% Cu, 0.03% O2, and less than 50 ppm metallic impurities.

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.
In Table A below, the intersection of the respective Lot Size and General Inspection Level indicates sample size code letter L. Then, referring to Table B, we locate row L, which indicates the required sample size of 200. To comply with AQL 2.5, no more than 10 units from that sample size …

Sep 12, 2013 Ok I know there is no relationship between sample size and lot size. But there are a lot of recommendations to use at least a sample size of 59 because of statistic evidence. I am preparing a rational who the recommendation of a attributive sample test is recommended on the base of 95% reliance and 95% confidence using a binomial distribution.
