Gold Production from Beginning to End tells about all four stages of gold production, from exploration and mining to processing and refining. It discusses the different types of gold deposits and how they are found, as well as drilling techniques and how deposits are classified. Other topics include mining methods, such as bulk extraction and sublevel stoping, and an overview of special techniques used to process refractory ore—the most difficult type of ore to process. Ultimately, this book tells about doré bars, gold purity requirements, and the exchanges that specialize in buying and selling gold.
