DOI: 10.1016/j.powtec.2020.12.035
Abstract: Abstract To improve the flowability of ultrafine-tailings cemented paste backfill (UTCPB) while keeping water content low, superplasticizers (SP) are usually used. The water film thickness (WFT) theory was introduced to investigate the flowability of UTCPB… read more here.

DOI: 10.1155/2019/5137092
Abstract: Due to continuous improvements in the beneficiation process, the size of tailings has decreased. In many mines, more than 50% of the total tailings are finer than 74 μm. Ultrafine tailings exhibit a slow settling velocity… read more here.
