2. The many ways mining activities impact biodiversity. Mining affects biodiversity at multiple spatial scales (site, landscape, regional and global) through direct (i.e. mineral extraction) and indirect processes (via industries supporting mining operations, and external stakeholders who gain access to biodiversity-rich areas as the result of …
Quarrying commodities. Exploration. Contacts. Quarries produce extractive minerals including sand, gravel, stone, shell or clay, although these materials are not considered extractives if they are used for industrial, agricultural and ornamental (dimension stone) uses. This includes exclusions for some clay (fireclay, bentonite or kaolin).
On 20 May 2022 the Department for Energy and Mining (DEM) issued a compliance order to Hanson Construction Materials regarding White Rock Quarry. The compliance order relates to White Rock Quarry's non-compliance with its mine operations plan in relation to offsite release of sediment-laden stormwater into Third Creek.

Published 9 April 2018. Chemistry. Rock Mechanics and Rock Engineering. This paper investigates fragmentation in an aggregate quarry in the light of the fragmentation-energy fan concept. Six blasts were monitored, located one behind the other in the same quarry area. The rock structure was blocky, the water level and the usage of explosives ...
Here are some strategies to consider, from Deloitte's "Mining spotlight on sliding productivity and spiraling costs.". 1. Strengthen mine planning. Refocus on high quality production by increasing cut off grades. Reduce capital expenditures in properties with lower production potential and shorter mine lives.
According to the Coalition for Eco-Efficient Comminution, comminution – the process of crushing and grinding ore – is by far the most energy consuming step in the mining process. It accounts ...

Where do you see energy-efficiency in the comminution circuit going? AB: There is only one way for energy efficiency in mining and mineral processing to go, and that is up.
As a general rule, the larger the reduction ratio that a comminution device is required to achieve, the less efficient it is. Comminution machines can be much more energy-efficient if they target a smaller size range, i.e. F80 to P80. Therefore, a really energy efficient circuit may mean three stages of grinding instead of only two and each ...
