Inactive Sulfide Ecosystems in the Deep Sea: A Review
Van Dover,Cindy Lee +1 more
TL;DR: The current state of knowledge regarding the ecology (microbiology and macrobiology) of inactive sulfides is reviewed in this article, where the attention is given to environmental management considerations where lack of knowledge impedes informed policy recommendations and decisions.
Journal ArticleDOI
Geological, Mineralogical and Textural Impacts on the Distribution of Environmentally Toxic Trace Elements in Seafloor Massive Sulfide Occurrences
TL;DR: In this article, in-situ microanalysis (EMPA) and laser ablation inductively coupled plasma mass spectrometry (LA-ICP-MS) were used to highlight the distribution of potentially-toxic trace elements (Cu, Zn, Pb, Mn, Cd, As, Sb, Co, Ni, Bi, Ag and Hg) within the sulfide deposits, their minerals and textures.

Improving Environmental Management Practices in Deep-Sea Mining
TL;DR: In this article, the authors highlight the use of the "mitigation hierarchy" as a suitable way to consider environmental management issues in the context of deep-sea mining and call for a more consistent approach by making some key recommendations and highlighting some outstanding issues.
Book ChapterDOI
Environmental Impacts of Nodule, Crust and Sulphide Mining: An Overview
TL;DR: In this paper, the authors investigated the impacts of deep-sea mining on the ecology of the deep ocean and found that organisms may struggle to recover from the impacts in some areas, whilst in other areas the impacts may be less.

Multiple-site adsorption of cd, cu, zn, and pb on amorphous iron oxyhydroxide
Mark M. Benjamin,James O. Leckie +1 more
TL;DR: In this paper, the strength of binding between a given metal and the surface may vary by an order of magnitude or more from one site to another, suggesting that the surface is composed of many groups of binding sites.

The kinetics and electrochemical rate-determining step of aqueous pyrite oxidation
TL;DR: In this article, a series of batch and mixed flow reactor experiments were performed to determine the effect of SO42−, Cl−, ionic strength, and dissolved oxygen on the rate of reaction of pyrite with ferric iron.

Oxidation of pyrite in low temperature acidic solutions: Rate laws and surface textures
Michael A. McKibben,H.L. Barnes +1 more
TL;DR: In this article, rate laws for the aqueous oxidation of pyrite by ferric ion, dissolved oxygen and hydrogen peroxide at 30°C in dilute, acidic chloride solutions were derived.

Reaction kinetics of the adsorption and desorption of nickel, zinc and cadmium by goethite. I. Adsorption and diffusion of metals
TL;DR: In this paper, the reactions of Ni, Zn and Cd with goethite were studied over a range of initial metal concentrations (10−6 to 10−4M), pH values (4 to 8), reaction times (2h to 42d) and temperatures (5 to 35°C).
