This year’s WALSIM symposium will be the tenth symposium on Water, Air, Land Sustainability Issues in Mining, Mineral Processing and Metal Extraction. The theme of the symposium will be focused on the technical advances being made by a wide variety of industries to promote more efficient and sustainable processes. In this regard, five major topics of relevance to the mining, minerals and metals industries are proposed as follows: towards zero waste, greenhouse gas reduction, water conservation, non-conventional resources and supply issues. Each of these topics is described in more detail below.
Towards Zero Waste: Mining, mineral processing and metal extraction can be integrated and this can lead to a circular economy that promotes the minimization of waste. Waste streams can in fact be considered as secondary resources of either valuable minerals or metals.
Greenhouse Gas Reduction: The various industries are trying to minimize greenhouse gas reductions. Papers are invited on the quantitative reduction of greenhouse gases, in particular carbon dioxide, for the mining. minerals and metals extraction industries.
Water Conservation: The conservation of water is of particular concern for the metal extraction industries and also for the environment. The water composition and its effects on the process, for example fresh water versus seawater, is an important consideration in mineral concentration processes.
Non-Conventional Resources: Landfills and other resources are being considered for metal extraction and this has become known as urban mining. Also, landfills release leachates from which metals could be recovered. Other non-conventional resources include deep sea polymetallic nodules.
Supply Issues: The supply of materials is becoming an issue due to a number of factors including geopolitics and supply-chain challenges. From obtaining a permit to start a mine to shipping raw materials around the world, the supply of materials is becoming a significant issue.
Papers concerning other relevant sustainability subjects, which do not fully align with the proposed symposium topics will also be considered. If a group of papers are submitted on a particular topic then a separate session can be added.
This symposium should be of interest to people in industry, academia, government, and research.
