Aggregates for Concrete

Synthetic aggregates may be either byproducts of an industrial process, in the case of blast-furnace slag, or products of processes developed to manufacture aggregates with special properties, as in the case of expanded clay, shale, or slate used for lightweight aggregates. Some lightweight aggregates such as pumice or scoria also occur naturally.

Low-Grade Phosphate Tailings Beneficiation via Organic ...

In this paper, the beneficiation of rejected phosphate washing sludges (Ps) was investigated using acid leaching methods. Chemical analysis showed that these sludges are a low-grade ore (15.84% P 2 O 5).The optimum milling parameters have helped to increase the P 2 O 5 grade to 18.51%. Then, the effects of three different organic acids (acetic, lactic, and citric …

Beneficiation - Wikipedia

In the mining industry or extractive metallurgy, beneficiation is any process that improves (benefits) the economic value of the ore by removing the gangue minerals, which results in a higher grade product (ore concentrate) and a waste stream ().There are many different types of beneficiation, with each step furthering the concentration of the original ore.
