About ore blending & stockpiles: Since the function of the stockpile is to act as an ore reservoir rather than as an ore processor, the action of forming a stockpile should have as little effect as possible on the material. Several undesirable effects are produced by discharging the material from too great a height above the stockpile.

at Swartberg was commissioned. The Swartberg mine is located 7 km from Broken Hill and ore is hauled by truck to the surface ore pad at Broken Hill. In this way, Black Mountain can maintain an annual production rate of 1.56 Mt/a (Figure 2). However, the blend of Swartberg ore with Broken Hill ore poses specific processing problems. The
Coal homogenization refers to the process of mixing coal to reduce the variance of the product supplied. This homogenization process is performed during the coal stockpiling operation. Although the terms blending and homogenization are often used interchangeably, there are differences as the definitions show. The most notable difference is that blending refers to stacking coal from different ...
The ore is then delivered to the crusher or the appropriate stockpile depending on the daily blending requirements. Kumtor has an active and dynamic blending program in close contact with the mill that adjusts the ore blend as required to maximize the gold recovery. MILLING. The current Kumtor plant flowsheet reflects the fine-grained nature of ...
Stockpile serves as a buffer between the delivery and processing, as a strategic stock to short-term disturbances or long term. Stockpile also serves as a process of homogenization or mixing coal and to prepare the required quality. Besides the above objectives in the stockpile is also used for coal memcampur order homogenization as needed.
