TLDR
In this review, recent advances in AMD prevention techniques like oxygen barriers, utilization of bactericides, co-disposal and blending, and passivation of sulfide minerals are discussed and recycling of mine tailings as construction and geopolymer materials to reduce the amounts of wastes for disposal are introduced.About:

Acid mine drainage formation and arsenic mobility under strongly acidic conditions: Importance of soluble phases, iron oxyhydroxides/oxides and nature of oxidation layer on pyrite
Carlito Baltazar Tabelin,Ryan D. Corpuz,Toshifumi Igarashi,Mylah Villacorte-Tabelin,Richard Diaz Alorro,Kyoungkeun Yoo,Simit Raval,Mayumi Ito,Naoki Hiroyoshi +8 more
TL;DR: This study observed the formation of a mechanically 'strong' coating on pyrite that suppressed the mineral's oxidation, and found that As mobility under acidic conditions was limited by its precipitation as ferric arsenate, scorodite, or a Fe/Al arsenate phase, including its strong adsorption to Fe-oxyhydroxides/oxides.

Eco-friendly geopolymer prepared from solid wastes: A critical review.
TL;DR: This review classifies the solid wastes utilized for geopolymers into three main categories: industrial waste, agricultural waste, and municipal waste and systematically disserts solid wastes-based geopolymer from the perspectives of structure, properties, and application.

Towards a low-carbon society: A review of lithium resource availability, challenges and innovations in mining, extraction and recycling, and future perspectives
Carlito Baltazar Tabelin,J.A. Dallas,Sophia Casanova,Timothy M. Pelech,Ghislain Bournival,Serkan Saydam,Ismet Canbulat +6 more
TL;DR: The demand for lithium has skyrocketed in recent years primarily due to three international treaties (Kyoto Protocol, Paris Agreement and UN Sustainable Development Goals) as mentioned in this paper, all of which are pushing for the integration of more renewable energy and clean storage technologies in the transportation and electric power sectors to curb CO2 emissions and limit the adverse effects of CO2-promoted climate change.

TL;DR: The results suggest that the flexibility and applicability of this new AMD treatment approach could be improved by controlling the dissolved Si concentration prior to the ferrite formation step.

Mechanism of geopolymerization and factors influencing its development: a review
Divya Khale,Rubina Chaudhary +1 more
TL;DR: In this paper, the authors present the work carried out on the chemical reaction, the source materials, and the factor affecting geopolymerization, and demonstrate that certain mix compositions and reaction conditions such as Al2O3/SiO2, alkali concentration, curing temperature with curing time, water/solid ratio and pH significantly influences the formation and properties of a geopolymers.

Microbial communities in acid mine drainage
TL;DR: Evidence for physiological synergy in iron, sulfur, and carbon flow in these communities is reviewed, and microbial and geochemical simplicity of these systems makes them ideal targets for quantitative, genomic-based analyses of microbial ecology and evolution and community function.
