Nickel waste tailings are produced during the hydrometallurgical leaching of nickel – cobalt ore slurry with concentrated sulphuric acid. They are classified by the Toxicity Characteristic Leachin...
To assess the average metal content of the pollution sources, it was assumed that they primarily originate from demolition and renovation wood waste flows (cf. Goldkuhl et al., 1994, The Swedish Environmental Protection Agency, 1996).According to available statistics, mainly for residential blocks, most demolition, refurbishment and renovation waste originates …
ment of large-volume mine waste streams are required (Yellishetty et al. 2008). One alter-native approach to the land disposal of large-volume mine waste entails the re-allocation of these wastes as feedstock for other uses. Such an approach is aimed at simultaneously minimising the waste burden and maximis-

1. Introduction This paper demonstrates that the business model (Magretta, 2002; Osterwalder et al., 2010; Zott et al., 2011) of Swedish municipally owned waste management companies (Corvellec et al., 2012) – i.e., how they generate their revenues (Plé et al., 2010) – leads them to be active on four different but interrelated markets.

The objective of this study was to investigate the impact of the waste rock dump at Trojan Nickel Mine on surface water quality. 1.2. Site description Mining of the sulphide bearing ore body at Trojan Nickel Mine which is located 90 km north of Harare (see Fig. 1), commenced in 1965, and the first nickel concentrates were produced in 1968.
The residual material was leached with 5% (v/v) sulfuric acid (H 2 SO 4) in the presence of 15% (v/v) hydrogen peroxide (H 2 O 2) to achieve maximum nickel dissolution, resulting in the recovery of 99% of aluminum as Al(OH) 3 with 99.8% purity and 99% of nickel as NiSO 4.6H 2 O.

Around 68% of all nickel available from consumer products is recycled and begins a new life cycle (reference year 2010); another 15% enters the carbon steel loop. However, around 17% still ends up in landfill, mainly in metal goods …
The motive behind these targets is primarily to attain the main aim of the legislation. Lindhqvist (2000) notes: "Collection and recycling targets are in these contexts secondary goals that are justifiable if they give the proper incentives for change of the products and product systems," (p. 129). In this paper, the definitions of the EC directive for packaging and …
Robust industrial and environmental policies are needed to ensure nickel's production becomes cleaner, including expanding nickel processing capacities in Europe, setting up mutually beneficial trade partnerships with …
Since some treatment technologies can generate highly toxic sludge and other waste products, the management of the generated waste was also considered. Some studies have focused on the treatment of wastewater at the laboratory level using the adsorption process. ... As, Zn, Al: Gold mine: Adsorption: 95.2, 93.7, 83.8 [117] Fe–Al bimetallic ...
In addition, the use of chemicals and reagents in nickel analysis are generally hazardous and will need to be appropriately managed Therefore, the proposed waste management plan is geared towards ...
The Waste2Place project, funded by Swedish Mining Innovation, is run by Frida Holst and Matt Baida of VAST Landscape Architecture. Together with ten partners from industry, experts and academia they attempt to address the long-term liability risk and, in many cases, costly ongoing maintenance, of current waste rock landform solutions.

For example, in Sweden, the boiler companies and the Swedish Energy Agency have funded a research programme to encourage the use of non-coal ash (Ribbing, 2007). Scientists, engineers, and researchers have offered an alternative solution for a better solid waste management by recovering the metals present in such solid wastes.

Nickel in a circular economy. The concept of a circular economy is generally understood to be "a regenerative system in which resource input and waste, emission, and energy leakage are minimised by slowing, closing, and narrowing energy and material loops.This can be achieved through long lasting design, maintenance, repair, reuse, remanufacturing, refurbishing, and …
A few examples of individual innovative relationships are: the use of coal fly ash as a binding agent in construction materials (Theissing, 1984), the creation of protein-rich feed or fuel from organic waste (Cičková et al., 2014), the use of surplus industrial heat in external organizations' production processes (Chae et al ...
