Electronic Initiation Dyno Nobel

Absolute control over initiation timing allowed Cadia to expand patterns and reduce powder factors by 17% without impacting mill throughput. Through clever blast design and system flexibility, Cadia was able to optimise burden relief, allowing for the best combination of blast movement, fragmentation and dig-ability.The oversize and primary crusher feed size distributions obtained from the SPLIT system were combined to estimate the ROM size distribution. 3. Size analyses from the SPLIT system Using conventional methods to size coarse material such as ROM ore, muckpiles, primary crusher products, etc., is extremely difficult and costly.Mine To Mill Optimization PDF Mill (Grinding) Mining

Reducing mine water requirements ScienceDirect

As shown in Table 2, the process water requirement for flotation is 116,667 m 3 /d, based on a flotation density of 30% solids by mass. This water requirement is met by a mixture of raw water, reused raw water discharged from primary uses such as cooling systems, and recycle water from the TSF or thickeners, shown schematically in Fig. 3.In Proceedings of the 39th Annual Canadian Mineral Processors Conference 2007 143 Not assumed was the possibility of less throughput sensitivity and cycling whenever the mill coarse ore feed stockpile was low and/or being pushed, such as when the primary crusher was down for maintenance (12 hours minimum scheduled every 2 Sag mill-operation-at-cortez evolution-of-liner-d-11 PDF

The purpose of the primary crusher is to reduce the ROM ore to a size amenable for feeding the secondary crusher or the SAG mill grinding circuit. The ratio of reduction through a primary crusher can be up to about 81. Feed ROM up to 1.5 m Product -300mm for transport to -200mm for SAG mill Feed Rate 160 to 13,000 tph . ReadmoreTypically, a SAG mill based circuit (P80 of 106 to 150 um) has media costs of around A$1/t. Providing the ore is amenable, the use of primary autogenous milling can reduce this cost by 30 to 40%. Autogenous milling is typically practiced in association with pebble crushing to improve circuit power efficiency.Sag Milling PDF Mill (Grinding) Mining Scribd
