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 "Geochemical Properties and Environmental Fate of Cyanide" is the third in the series of six courses. This course covers the attenuation mechanisms applicable to cyanide and their effectiveness in different metallurgical and environmental contexts, including surface ponds, tailings, heap leach, soil and groundwater. 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.

Reclamation and Revegetation for Mines in Arid Climates is intended for environmental specialists in private practice and governmental agencies. The purpose of this course is to present mining related reclamation based on practical and actual experience. The course presents actual mine reclamation practices that worked or didn’t work. The focus of this course is on base and precious metal mining operations in the western US, but the reclamation practices are applicable in other regions of the US and abroad. The course presents all aspects related to reclamation of mines from the initial baseline studies to final reclamation and bond release. Much of the approach is based on requirements by governmental agency rules and regulations. Reclamation programs are based on site specific conditions and baseline studies. These studies and surveys may start by examining natural revegetation in the region and on old mine disturbance. The goal is to create systems based on ecosystem analysis (prior knowledge) and sound ecological processes and patterns. The ecosystems established will be stable and sustainable based on the environmental settings, since local ecosystems are a function of climate, soils, biota; animals/vegetation, time, cycles, and energy flow. The goal is to match current ecosystems and promote diversity in compatibility with the surrounding landscape.

In theory, mine closure is simple; in practice, it is difficult. In this course, we will start with the simple and then proceed to the more difficult, which we will explain in terms that will enable you to deal with the many issues that arise as you plan and implement mine closure. The simple part of mine closure may be set down as three objectives: remove equipment and structures; stabilize waste piles; and control spread of pollutants from the closed site. As we shall see as we progress through this course, these three simple objectives quickly give rise to many questions and knotty issues, including: Who pays? Who says enough is enough? And, What is to become of the site in the long term? Many more related and difficult issues arise. Reading only this course will not enable you to solve all the problems. Each mine site is unique and demands a unique closure plan and approach. You will undoubtedly have to formulate the specifics of the closure plan for your mine by way of many studies, meetings, reports, and deep deliberations. This course will attempt to set down the current state of ideas, practice, and possibilities, so that you are empowered to move forward to success at the mine where you are part of a team charged with mine closure.

Regardless of world market conditions, to win, sustain, and maintain the right to mine is all about sustainability. Waste water management is emerging as the pre-eminent sustainability issue within the global energy and mining resource industries, i.e. related to the following activities: coal bed methane water (CBMw), LNG waste water, oil shale water, coal mining, open pit and underground mining, natural gas extraction, hydrocarbons, metallurgical ore processing, surface and underground earthworks and drainage, and underground coal gasification. This waste water management course has been designed to educate people from the mining, metallurgical, oil, and gas sectors who have to manage waste water issues associated with their day to day activities. This course will equip them with a basic knowledge and understanding of water management tools and strategies, including knowledge of the common terms associated with the water treatment industry. The course does not replace professional advice; however, it does allow informed discussions with professionals. Traditionally, waste water management is encountered in most energy resource extraction, mining, and ore processing activities. All of these industries are facing increasing scrutiny, regulation, competition for land access, and "angst" from local landholders (farmers) and stakeholders (agricultural and urban development). These crucial stakeholders have the perception of their water resource being potentially polluted, and/or reduced in available volume by the resource industry unless proved otherwise. They are concerned about sustainability, potential pollution issues, and access to the water resource itself. Water is the principal vehicle by which potential pollutants in untreated wastewater can be carried from these industries to local habitats potentially impacting on the local surface areas, the local environment, and underground aquifers—especially where this water is accessed and applied through traditional practices such as irrigation. In extreme cases, the polluted water could impact on human life itself. So, in order to demonstrate responsible stewardship over the water resource being extracted, this course gives a practical framework in order to create a robust sustainable water management solution (plan) that has the components of assessing the: raw waste water quality; final stage target water quality; potential beneficial uses for the water; treatment options to achieve the targets outlined above; and a risk assessment process that avoids harm to the environment while realising long-term sustainable benefits.

This course provides a non-technical introduction to the use and management of cyanide on a global basis. The course is designed to provide the global picture of cyanide use and how it compares with other chemicals used around the world. Cyanide is used in gold mining operations, however, there is much confusion regarding the real impact of cyanide use in mining. This course attempts to dispel the myths and mysteries surrounding cyanide and provide reliable facts and figures. The course begins with an examination of the production, use, treatment, and transportation of cyanide worldwide, followed by discussions of its technical properties, risks, and management. Subsequent courses in the Cyanide Management in Mining series detail specific technical aspects highlighted in this introductory course.

This course is intended for a broad-based audience of managers, professionals, students and concerned stakeholders in mining who require an understanding of the concepts and issues of sustainable development. Sustainable Development in Mining focuses on the underlying concepts and issues that apply specifically to the mining industry. Included are the sustainable development concepts of... economic growth that preserves the earth's biophysical integrity; optimization of the societal benefits of economic development; system quality... which systems should be preserved/improved; a more equitable distribution of the benefits and burdens of economic growth ... both within the present generation and between present and future generations; greater public participation in the decision-making process. These concepts are illustrated by numerous case studies and examples from mining projects, and further supported by a discussion of mineral consumption, recycling and resource depletion.
