The benefits of continuous casting are increased yield, higher quality, energy savings and a reduction in both capital and operating costs. Ingot-poured moulds are stored in soaking pits (i.e. underground ovens with doors), where ingots can be reheated before passing to the rolling mills or other subsequent processing (figure 73.4). Recently
How does recycling save energy? PDF version. Extracting and processing raw resources (wood, oil, ore) to make usable materials (paper, plastic, metal) requires a lot of energy. Recycling often saves energy because the products being recycled usually require much less
initial benchmarking of an operation’s practices, SRK can advise on how value-added blasting will deliver improvements in both mill capacity and overall consistency of performance. SRK employs modelling tools to simulate the effect of upstream changes in blasting and crushing on grinding circuit tonnage. To demonstrate the expected improvements, extended plant trials of higher-energy blasted
This mine is an open pit mine producing 5,000 tonnes ore and 5,000 tonnes waste per day. Rock characteristics for both ore and waste are typical of those of granite or porphyritic material. Operating conditions, wage scales, and unit prices are typical for western U.S. mining operations. All costs listed are in 2012 US$. The key design criteria

Energy cogeneration in sugarcane industries located in Brazil is a practice that has been growing in last years. With the adoption of energy cogeneration in the sugar and alcohol sector, the sugarcane industries are able to supply the electric energy demand needed to operate, and generate a surplus that can be commercialized.
The operation of the mine to recover the ore begins and continues as long as the company operating the mine finds it economical to do so. Once all the ore that the mine can produce profitably is recovered, reclamation begins to make the land used by the mine suitable for future use. Mining techniques
