• The importance of coarse-ore stockpile design.

    This is the ideal case; however, we have observed that in some large mining projects (recent and not so recent), the coarse ore stockpile has been designed without proper consideration of the ore’s flow properties. In most of these cases the result has been

    Automating material tracking through the coarse ore

    Automating material tracking through the coarse ore stockpile yes, we can. During a recent CIM Webinar, Steven Putt offered a solution for a common obstacle in mine to mill tracking; loss of information in the coarse ore stockpile prior to the grinding circuit.

    Fine Ore Storage Bin and Stock Pile

    Let’s begin with fine ore storage bin or stockpile, get it out of the way and then proceed to grinding. You would think that there isn’t that much to learn about when talking of fine ore storage, after all, all that this area is really for is to provide surge capacity for each of the circuits. True, but there are a couple of things that operators should know about. To begin with, I would

    Ore Stockpiling Why are we doing this again?

    28/04/2016· The problematic ore might be stockpiled until sufficient inventory allows one to process that ore (i.e. campaign) through the mill. Such stockpiles will only grow as large as the operator allows them to grow. At any time the operator can process the material and deplete the stockpile. Be aware that mining operations might still be mining other ore types, then those ores may need to be
