A Novel Method to Limit the Adverse Effect of Fine Serpentine on the Flotation of Pyrite
TL;DR: In this article, a novel method to limit the adverse effect of fine serpentine on the flotation of pyrite was investigated, and the results of particle size measurements and rheological measurements exhibited that the addition of KAl(SO4)2·12H2O increased the particle size of serpentine buta hrdly affected the particle number, and then limited the formation of the serpentine-pyrite aggregates.

Effect of dissolved oxygen on the sulfidization flotation of smithsonite
TL;DR: In this paper , the authors investigated the sulfidization process and sulfide products on smithsonite surface under various DO conditions by means of in-site electrochemical quartz microbalance (eQCM), zeta potential tests, and X-ray photoelectron spectroscopy (XPS) analysis.

Partial Non-Orthogonal Multiple Access: A New Perspective for RIS-Aided Downlink
TL;DR: In this article , a reconfigurable intelligent surface (RIS) aided partial non-orthogonal multiple access (P-NOMA) downlink is investigated, where the passive beamforming on the RIS is designed for serving paired user equipments (UEs), with their signal frequencies partially overlapped.

On the Performance of Cooperative NOMA Downlink: A RIS-Aided D2D Perspective
TL;DR: An RIS-aided cooperative non-orthogonal multiple access (C-NOMA) system serving two power-domain users, where a near user as a decode-and-forward (DF) half-duplex (HD) relay performs device-to-device (D2D) communications for a far user.

Understanding the impact of ammonium salt on the sulfidization of smithsonite from coordination chemistry
TL;DR: In this article , a systematic investigation from coordination chemistry was performed to investigate the principles met by the ammonium salt to enable it to impact the sulfidization of smithsonite.
