Gold Mining and Processing – Blending Optimization for Mill Throughput and Recovery. Seasonal conditions pose production challenges Historically, ore feed to the mill was exclusively from stockpiles four months of the year. During the period, net recovery averaged percent, throughput 671 tons per operating hour and uptime per day was 96 percent. The project

The average grade of a particular stockpile is the average grade of ore mined during a certain stockpile building period. Ore from the stockpiles is blended to the required grade before feeding to a stackerreclaimer for further homogenisation.

Its key assets are the Caylloma silver mine in southern Peru, the San Jose silvergold mine in Mexico and the Lindero Project, The mine initially operated by drawing ore from its coarse ore stockpile, and as the stockpile decreased, the mine restarted using a reduced task force. In March, 2020, construction activities at Lindero were also halted temporarily. However, Fortuna said it

Coming back to the coarse ore stockpile example, Putt recommends hardrock miners add another filter to their existing blending process to help improve results. "It is about adding a mill risk factor to an existing grade control program; getting the engineers to plan the mining regime in a certain way to effectively prepare the mill for the material being fed into the coarse ore stockpile

The final step is to complete the stockpile account for contained gold. Similar to the ore stockpile account in screenshot 4, there is an opening balance and a closing balance for this account. Adding to the stockpile is the contained gold from the ore mined. Depleting the account is the contained gold of the ore milled.

The ore to be milled is managed through a number of stockpiles that receive ore of different metallurgical character and of different grade ranges and thus allow blending of the mill feed. A gyratory crusher reduces the ore to minus 1520 centimetres. The ore is then fed to a coarse ore stockpile from which it is reclaimed for grinding, first to a semiautogenous ("SAG") mill and then to a

The Kirunavaara ore, Leveäniemi ore and the Mertainen ore have been the considered for ore blending purposes and as a preliminary assessment to the feasibility of blending these ores, an investigation into the different behaviors associated with the ores in comminution and the resulting product quality from the magnetic

Mining Stockpile Inventory Measurement. Stockpiles must be measured to determine contained volume and weight of the commodity contained within. SGS uses Total Station, a stateoftheart laserbased instrumental method, to measure stockpiles in which the entire surface area is visible.

Test work on bulk lowgrade gold ore stockpile samples from Central Norseman Gold Proprietary Limited has been conducted, indicating high gold recoveries as well as high material rejection rates. A financial model, based on these results, evaluates grade sensitivity and identifies a minimum stockpile grade for adequate financial returns. The base case modelling estimates that the exstockpile

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 rathole formation, live capacities much lower than the desired value, and, as a consequence, the need for bulldozers or other mechanical

Blending on the coarse ore stockpile happens according to a userspecified recipe. In other words, the user specifies a percentage for each pile that is converted into a rate at which the pile is drawn down. This allows balancing out periods of low or high grade by blending in stocked ore.

Whereas this design suits the mining process and is operationally simple, there can be little confidence in the grade of the ore that is fed to the crusher. This makes shortterm grade control difficult and reconciliation back to the mine face imprecise. Welldesigned and operated precrusher stockpiles can overcome these deficiencies. The different types of grade variability in mining are

Blending more value into your mining operation Yes, we all want to get the best value out of our mines. Typically, we aim to produce an optimal schedule where the blasting is well executed, the mine fleet is effectively utilized, the ore feed is on target and the volume of stockpile material is sufficient to meet the right blend for each product.

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. There is a wealth of information in the data that sits unprocessed and unconnected at mine sites. In the presentation he explained

Stackers are bulk stockpiling machines that are used to stack material in stockyards in different shapes according to specific requirements. A stacker''s function is to stack or pile material on to a stockpile for later reclamation and use a reclaimer is generally used to reclaim or recover the stockpiled material.

· MINE SCHEDULING Ore blending from different stockpiles that represents different nickel grades usually done in the operation. Mine scheduling is commonly used to determine the sequence of mining excavation from a nickel deposit, also to consider what happens to the loose material after it has been mined.

Blending: Blending stockpiles may be used where a processing plant needs a certain quality of feed material with respect to head grade or contaminant ratios (silica, iron, etc.). Blending stockpiles enables the operator to ensure the plant feed quality to be within a consistent range.
