Grade control in hard-rock open pit mining is the process of determining the destination for the mined material. Numerical studies are undertaken to show how grade control can be improved, that is, less ore sent to the waste dump and less waste sent to the mill. The improvements in four aspects of grade control are proposed: (1) the grade ...
Sampling is a critical component throughout the mine value chain; it includes the sampling of both in-situ and broken material for geological (resource and grade control), geoenvironmental, and geometallurgical purposes [1,2,3,4,5,6,7].Sampling errors generate both monetary and intangible losses [3,8].The data produced must be fit-for …
In 2021, Antamina produced 445,300 tonnes of copper, 462,200 tonnes of zinc and 4.9 million pounds of molybdenum. Mining and processing. Antamina employs an open pit, truck-and-shovel operation for mining. The ore is crushed within the pit and transported via a 2.7km tunnel to a coarse ore stockpile at the mill.
When the exploration is done, and the ore excavated and brought to the surface, all your plans for profitability hang on one last piece of the puzzle – how well do you really understand that ore body you've pursued so hard? Good Grade Control is essential to increasing profitability, reducing costs and waste, and saving time.

Initial ore grade control was based on blast hole samples collected in two stages by an "automatic" sample collection device (sometimes called a rocket sampler). A sample was collected for the top 3 m (10 ft) in a holes and then the bag was changed so that a sample was collected for the lower 3 m (10 ft). Each of these samples was …
advantage of reconciling grade control and mineral resource is the ability to produce a total mass balance comparison including ore, low-grade mineralisation and waste. 5.3. Reconciliations between Ore Reserves, Grade Control and Production The adoption of this method requires that both grade control and ore reserves estimates be based on the …

At most mines, the grade control program has three principal goals: To forecast the grade or physical characteristics of the material to be mined during the next month or year. This is a cooperative effort involving all of the mine staff, and is the first step in preparing the financial projection for the period in question.
En Antamina, luego de un proceso de reflexión hemos reestructurado nuestro Marco Estratégico. Debido a ello, es importante mencionar que este nuevo esquema sigue un proceso "causativo" con 4 dimensiones, representadas mediante nuestra Concentradora y sus 4 pisos, uno para cada dimensión estratégica.
However, as stated before, ore grade in mines is decreasing over time. According to our model, if the ore grade decreases one order of magnitude (to 7.51·10 −1 g-Au/t), the total energy to produce that same amount of metal would be 1.28 TWh. We must note that this value is almost equal to the total annual energy production of …
