A Study of High‐Emission Industries: How Policy, Strategy, and Technology Shape Corporate Social Responsibility Toward Carbon Neutrality

Corporate Social Responsibility and Environmental Management, EarlyView.
ABSTRACT The extant carbon neutrality (CN) literature largely offers macro‐ or meso‐level analyses, providing limited insights into implementation experiences that could inform granular policymaking and industry strategies. To address this gap, we examine the lived CN experiences of firms in the transportation, energy, manufacturing, and construction ...

Investigating the Effect of Zero Prewetting Time on Rougher Flotation of Coal Tailings [PDF]

Iranian Journal of Materials Science and Engineering, 2022
The beneficiation of coal tailings is usually difficult by common oily collectors in the flotation process, so it is necessary to use a suitable method for clean coal recovery from coal tailing dams. Thus, this study was aimed to investigate the behavior

Uniaxial compressive strength prediction and ratio parameter optimization of titanium tailings composite backfill materials using intelligent hybrid models

Deep Underground Science and Engineering, EarlyView.
Based on the 90 datasets, ERT and four optimization algorithms were used to build four hybrid models to predict the UCS of the backfill body. The SMA‐ERT model was the most effective model, and it can reliably guide the design of the backfill ratio parameters. Abstract This study analyzed the feasibility of using titanium (Ti) tailings as a backfilling
