The cyanidation process for the extraction of gold and silver from ore has been employed since 1898 when it was first used in New Zealand and Africa and soon after in the United States. It is a very efficient process capable of extracting gold in amounts of less than one percent of an ounce from a ton of rock with over 90% efficiency. Because of the environmental risks, a cyanide management plan is of critical importance to a mining operation. The lack of such a plan, in some cases, has contributed to adverse environmental incidents involving cyanide. The United Nations Environment Programme (UNEP) is developing an international code for the management of cyanide. Implementation and adherence to this code, augmented by experienced scientific and engineering judgment, will help reduce both the number and severity of environmental incidents involving cyanide. The "Cyanide Management in Mining" courses attempt to provide the user with the necessary background for development of a cyanide management plan that meets the unique requirements of each operating mine. The full complement of courses in the series includes: Chemistry of Free and Complexed Cyanide Analysis of Cyanides Geochemical Properties and Environmental Fate of Cyanide Toxicity and Environmental Properties of Cyanide Water Management and Discharge Strategies Treatment Technologies for Cyanide and Related Compounds "Treatment Technologies for Cyanide and Related Compounds" is the last in the series of six courses. This course discusses cyanide treatment technologies, including cyanide destruction, biological treatment, cyanide recovery, natural attenuation and treatment of related compounds. This course comprises 12 viewing sessions, each of 30 - 60 minutes duration, plus supporting figures, tables and references, and three interactive reviews that confirm achievement of the learning objectives.

Summary Large volumes of data is often generated and captured in mining. However, it is uncommon for the value that this data contains to be fully uncovered and utilised to improve processes. The report “How digital innovation can improve mining productivity” by McKinsey & Company (2015) found that less than 1% of operational data obtained by mining companies is appropriately used. This webinar will enable participants to apply theoretical knowledge of statistics to resolve applied mining problems.  Participants will gain an understanding of what data to collect, how to measure it, and with what frequency? The data cleansing, validation, exploration, visualisation and integration phases will also be presented. In doing so, participants will be exposed to excel spreadsheets in order to appropriately find patterns, gain insights and communicate results. A number of case studies will be presented which demonstrate how data driven decision making can be unitised to improve mining processes. This course requires participants to undertake numerous calculation based exercises to effectively demonstrate the impact of each of the key levers that will be addressed. All participants will be provided with template/pre-filled excel spreadsheets to minimize time spent on data entry. Good use of excel is therefore required. Duration:     5 Hours Access:       90 Days Price:           $399 USD Category:    Mining Who This Course is For This course is designed for participants with mining industry exposure that are genuinely interested in using data to find patterns and gain insights into how these can potentially improve mining processes. It is also recommended for mining professionals who want to refresh their knowledge on data analytics. This may include but not limited to the following: Mine planners/schedulers: To make better assumptions relating to future productivity, machine and operator performance. Maintenance planners: Useful for understanding trends in machine failure and downtime data.

This course refers to the generic mining method of sublevel stoping. The most commonly used sublevel stoping mining methods are sublevel open stoping, long-hole open stoping or blasthole stoping, and vertical crater retreat (VCR). Variations of this method include vein (Alimak) mining, transverse stoping, Avoca and longitudinal mining. Sublevel stoping accounts for more than 60% of all underground production in North America. This is largely due to the developments of extension steels, hollow tube and special long-hole rock drills, and ITH drilling techniques requiring less development and greater production capacities. Several variations exist; however, characteristic to this method is the development from a top drill drive and removal of muck from a draw level below for a steeply dipping stope. The variations of the method are selected to suit the ground conditions and operational requirements of the mine. This course presents the features, design requirements, design guidelines and application of the different sublevel stoping methods.

Mining involves the design, construction, operation, and closure of many geotechnical structures, including: access roads, structural building pads and foundations, ponds, tailings facilities, heap leach pads, and waste rock dumps. Geosynthetics are polymeric materials used extensively in mine geotechnical structures to enhance the performance of such structures. Geosynthetics are used in conjunction with soils and rocks to increase the overall strength of these materials, to control seepage from mine wastes and through soils and rocks, and to separate soils of different gradation and hence to limit piping and potential failure of soil structures. This course introduces you to the types of geosynthetics used in mine structures, to the ways in which geosynthetics may be used to build safe mine structures, and to the many details that will make it possible for you to use geosynthetics at your mine to reduce costs and protect the environment. This course describes many case histories of the successful use of geosynthetics in mining, thereby introducing concepts, ideas, details, and practical applications that you may copy or adapt to the specifics of your mine's needs and facilities.

This introductory course is intended for anybody involved in mining who has to manage, review, pay for, design, construct, operate, or close a geotechnical structure at a mine. Included in the mining-related geotechnical structures you will study in this course are the obvious: tailings impoundments, waste rock dumps, and heap leach pads. Once you have finished this course you will know enough to deal with anything on the mine that is made of soil, rock, and those modern materials called geosynthetics. This course is not intended to make you into a geotechnical engineering specialist. It will introduce you to and provide you with plenty of practical information and knowledge about those aspects of geotechnical engineering that occur at every mine. This includes geotechnical characterization of a site, soil characterization and properties, the design of geotechnical structures, and the construction, operation, and closure of mining facilities made or consisting of soil, rock, and geosynthetics. The following primary aspects of geotechnical engineering are covered for each of the major geowaste structures at a mine: Site Exploration Soil Characterization Soil Performance Design and Construction Operation of Mine Geowaste Facilities Closure of Mine Geowaste Facilities Summary of Geotechnical Factors The course includes numerous case studies from the author's extensive experience.
