Evaluation of the Use of Recycled Vegetable Oil As a Collector Reagent in the Flotation of Copper Sulfide Minerals Using Seawater
recycling Article Evaluation of the Use of Recycled Vegetable Oil as a Collector Reagent in the Flotation of Copper Sulfide Minerals Using Seawater Felipe Arcos and Lina Uribe * School of Mining Engineering, University of Talca, Talca 3460000, Chile; [email protected] * Correspondence: [email protected]; Tel.: +56-220-1798 Abstract: Considering sustainable mining, the use of seawater in mineral processing to replace conventional water is an attractive alternative, especially in cases where this resource is limited. However, the use of this aqueous medium generates a series of challenges; specifically, in the seawater flotation process, it is necessary to adapt traditional reagents to the aqueous medium or to propose new reagents that achieve better performance and are environmentally friendly. In this research, the technical feasibility of using recycled vegetable oil (RVO) as a collector of copper sulfide minerals in the flotation process using seawater was studied. The study considered the analysis of the metallurgical indexes when different concentrations of collector and foaming reagent were used, considering as collectors the RVO, potassium amyl xanthate (PAX) and mixtures of these, in addition to the methyl isobutyl carbinol (MIBC) as foaming agent. In addition, it was evidenced that the best metallurgical indexes were achieved using 40 g/t of RVO and 15 g/t of MIBC, which corresponded to an enrichment ratio of 6.29, a concentration ratio of 7.01, a copper recovery of 90.06% and a selectivity index with respect to pyrite of 4.03 and with respect to silica of 12.89. Finally, in relation to the study of the RVO and PAX collector mixtures, it was found that a mixture of 60 g/t of RVO and 40 g/t of PAX in the absence of foaming agent presented the best results in terms of copper recovery (98.66%) and the selectivity index with respect to pyrite (2.88) and silica (14.65), improving Citation: Arcos, F.; Uribe, L. -

Greenhouse Gas Impact of Marginal Fossil Fuel Use
Greenhouse gas impact of marginal fossil fuel use Greenhouse gas impact of marginal fossil fuel use By: Arno van den Bos, Carlo Hamelinck Date: 12 November 2014 Project number: BIENL14773 © Ecofys 2014 by order of the European Oilseed Alliance (EOA), the European Biodiesel Board (EBB) and the European Vegetable Oil and Proteinmeal Industry (FEDIOL) ECOFYS Netherlands B.V. | Kanaalweg 15G | 3526 KL Utrecht| T +31 (0)30 662-3300 | F +31 (0)30 662-3301 | E [email protected] | I www.ecofys.com Chamber of Commerce 30161191 Summary Biofuels represent a major option to reduce greenhouse gas emissions from the transportation sector. When assessing the benefits of biofuels, they are compared to the fossil fuels they replace. In the framework of the European Renewable Energy Directive and the Fuel Quality Directive, this is done by comparing the lifecycle greenhouse gas emissions of biofuels to a ‘fossil comparator’. This fossil comparator is based on the average greenhouse gas intensity of fossil fuels brought on the EU transportation market. Unconventional oils such as extra heavy oil and bitumen (tar sands), kerogen oil (oil shale), light tight oil (shale oil), deep sea oil and synthetic products such as gas-to-liquids and coal-to-liquids, typically have higher carbon footprints than conventional oil mainly because the effort required to extract, refine and/or synthesize them is much larger than for conventional oil. As the share of these unconventional oil-based fuels gradually rises in the total fuel supply over time, the greenhouse gas footprint of the average fuel consumption also rises. Even for conventional oil production fields, because larger existing fields get depleted, the extraction efforts increase while smaller fields are taken in operation. -

This guide is intended for use in teaching an introductory course in manufacturing materials and processes. The course centers around four basic materials--metallics, polymers, ceramics, and composites--and seven manufacturing processes--casting, forming, molding, separating, conditioning, assembling, and finishing. Concepts and classifications of material conversion, fundamental manufacturing materials and processes, and the main types of manufacturing materials are discussed in the first section. A course content outline is provided in the second section. The remainder of the guide consists of learning modules on the following topics: manufacturing materials and processes, the nature of manufacturing materials, testing materials, casting and molding materials, forming materials, separating materials, conditioning processes, assembling processes, finishing processes, and methods of evaluating and analyzing products. Each module includes information about the length of time needed to complete the module, an introduction to the instructional content to be covered in class, performance objectives, a day-by-day outline of student learning activities, related diagrams and drawings, and lists of suggested textbooks and references. -
