2018/3/253 Implementing an Ore Reconciliation System Supported by SPC Grade Control Model The grade control model is typically used for day-to-day production planning. In many operations, the grade control model can be defined from the short range model as ore

When iron ore is crushed and split into lump and fines components, there are systematic differences between the lump and fines grades. Generally the lump product is richer in iron and lower in the other minerals, compared to the fines product. The grade differences

Antamina, located at latitude 9 32' S and longitude 77 03' W in the Ancash Department of north-central Peru, is the largest known Cu-Zn skarn ore deposit. It incorporates a mineral reserve of 561 Mt, which has an average grade of 1.24 percent Cu, 1.03 percent Zn, 13.71 g/t Ag and 0.029 percent Mo, calculated at a 0.7 percent Cu equiv cutoff grade.

During exploration, grade control is a mining process to quality check and control the grade and variability of an ore. The purpose of grade control is for mining companies to understand and document any variability in their sampling and their ore reserve, considering the many facets of data collection before mining begins.


Reserves Resources

Antamina Open pit reserve estimates were prepared assuming long-term metal prices of US$3.084/lb copper, US$1.08/lb zinc, US$8.7/lb molybdenum and US$17.39/oz. silver. Open pit and underground resource estimates were prepared assuming long-term metal prices of US$3.30/lb copper, US$1.23/lb zinc, US$10.0/lb molybdenum and US$19.95/oz silver.

2020/5/27The Antamina copper and zinc mine in Peru has resumed operations following its shutdown due to the Covid-19 pandemic, shareholder Teck Resources said. The Vancouver, Canada-based miner, which has a 22.5% stake in Antamina, said that a reduced operating workforce had

Grade-control geologists use this information to minimize the loss of valuable ore and reduce waste fed to the mill, saving grinding energy and processing costs. The Results? Red Dog piloted blast movement monitors in 2016 and found that reducing ore losses in one blast paid for the whole pilot.

Mining geologists perform ore grade control in underground mining operations to figure out where the most profitable ore bodies are, in terms of location and mineral concentration variability. By performing ore grade control, mining operators are also reducing risk because they are checking for quality and variability of an ore, which gives them a better understanding of their material.

2019/1/1At Antamina, a Miocene quartz-monzonite porphyry intrusion created a skarn ore body hosted in Cretaceous carbonate limestone, marble and hornfels (Love et al., 2004). The two on-site waste-rock storage facilities are currently hundreds of meters tall, several kilometers wide and growing: by planned mine closure in 2029, the mine is expected to have produced 2.2 billion tons of waste rock

Antamina zinc output to jump over guidance in 2020 as mine hits new ore body The world's third biggest zinc mine, Antamina, is set to challenge for the top production spot next year. Peru's Antamina, which is co-owned by BHP, Glencore, Mitsubishi Corp and Teck Resources, will produce close to a million tonnes of zinc concentrates in 2020, sources told Fastmarkets.

By performing ore grade control, mining operators are also reducing risk because they are checking for quality and variability of an ore, which gives them a better understanding of their material. Portable XRF instruments provide fast acquisition of geochemical data for ore deposit modeling, easily determining elemental constituents for most natural low concentration samples, as well as high

Ore-control procedures are designed to allow mining of several ore types simultaneously but enabling one type to be sent to the concentrator at a time in order to maximise recoveries. Before production began, ore grade-control guidelines were also established to include the definition of blasthole logging and sampling procedures, as well as daily geostatistical modelling of the active mining

Ore deposits are inconsistent in nature, having high concentrations of metals in one area but much lower concentrations in others. Mining geologists perform ore grade control in underground mining operations to figure out where the most profitable ore bodies are, in

The Company's Ore Reserves and Mineral Resources have increased above net depletion as a consequence of resource extension drilling at Gwalia and revision of the Simberi geological model (Figures 1 2). At Simberi, Ore Reserves have been reduced after
