Apr 03, 2014 Field-portable x-ray fluorescence FPXRF instruments provide fast acquisition of geochemical data for mine mapping and ore deposit modeling. FPXRF is an established technique for easily determining elemental constituents for most natural low concentration samples, but its now emerging as an effective analytical tool for high grade ore ...
An ore is mixture of a metal or a mineral with impurities or waste material. In order to find out if a mine is worth exploring, a sample of the ore is taken to a laboratory to determine the percent mineral of interest through colorimetric method. Colorimetric measurement of copper will be done using the Vernier colorimeter. Figure 1 Copper Ore.
Jun 30, 2021 Historic Copper Mine. The Star Point target is the site of a high-grade, near-surface copper oxide tenorite mine that operated from the late 1940s through the mid-1950s. The ore produced there was shipped to a smelter in Utah for processing, but
Field portable XRF is a very reliable and effective tool to analyze any type of sample not only in the exploration stage low grade but also in the ore grading stage high grade. For concentrated mineral samples, the UserMethod can often provide reliable and accurate data, and will read results directly on the instrument screen once a UserMethod is uploaded, thus providing the instant results required on the production line for maintaining the correct grade

May 03, 2021 Kamoa-Kakula to Begin Copper Production Within a Month. Mining crews deliver a record 409,000 tonnes of ore grading 5.71 copper in April, including 121,000 tonnes grading 8.40 copper from the centre of the Kakula Mine. Pre-production ore stockpiles now hold three million tonnes grading 4.74 copper, containing more than 140,000 tonnes of copper.
May 26, 2021 In April, the Kakula Mine mined 357,000 t of ore grading 5.7 Cu, including 121,000 t grading 8.4 Cu from the mines high-grade centre. Kakula, Ivanhoe says, is projected to be the worlds highest-grade major copper mine, with an initial mining rate of 3.8 Mty, ramping up to 7.6 Mty in the September quarter of 2022.
According to Cox and Singer , the average copper ore grade in the mine x m was 1.67 around 1990 and in the case of the 25 copper mines analyzed, the average ore grade is 1.48. These selected mines produced more than 5 million tons in 2009, which corresponded to 32 of the total world production that same year 42 .

Nov 10, 2017 that operated from 1956 to 2007. A total of 4.4 million tonnes of ore was extracted from the underground operation grading 8.26 gt gold for 1.17 million ounces of gold, 5 gt silver for 607,000 ounces of silver, and 0.25 copper for 28.7 million pounds of copper Dor Copper
May 25, 2021 Porphyry copper-grade tonnage curve. In the graph above, assume a hypothetical deposit of 1 billion tonnes grading 0.5 copper. Until the mid-2000s, a typical copper grade was 0.4, meaning everything to the left of the dashed line was considered waste rock. By 2014, the cut-off grade is reduced to 0.25.
In 2018, the operation produced approximately 58.6 kt of copper and 121 koz of gold, or approximately 82 kt of copper equivalent3, at co-product cash costs of 1.74lb and 388oz gold equivalent, respectively. Since production commenced in 2007 to the end of 2018, the operation has processed 225 Mt of ore grading 0.38 copper and 0.33 gt gold,
The Falcon Gold Mine, located to the immediate west of unpatented mining claim 4278989, and not on the Copper Prince Property, was discovered prior to 1900 and operated intermittently until the late 1930s or early 1940s.
