Infrastructure and Construction Materials Guide — Aggregates
Aggregates are a broad category of construction materials. In terms of tonnage and number of quarries and mines world-wide, aggregates represent the largest mineral production tonnage excluding energy minerals. Range of grain/rock sizes Concrete sand and asphalt sand have a grain size of 4.75 mm (0.18 inch) to 0.075mm (0.003 inch).
Study of the optimal aggregate blending model for quarries
The quality of concrete is extremely important for the construction and mining sectors. One of the most important factors determining the quality of concrete depends on aggregates, which are not always homogeneous. On the other hand, there is an obligation to use aggregates obtained from different quarries. In such cases, the …
Mine-to-Mill Optimization of Aggregate Production
Mine-to-Mill optimization is a total systems approach to the reduction of energy and cost in mining and processing. Developed at the Julius Krutschnitt Mineral Research Center in Queensland, Australia, the Mine-to-Mill approach attempts to minimize energy consumption through optimization of all steps in the size reduction process. The approach involves …
