When a mining company calculates its cash cost, it takes total production costs and subtracts various items including what they call, "Byproduct credits." All silver mining companies produce additional metals (included in the ore) such as copper, lead, zinc and gold. For example, Endeavour Silver recorded a cash cost an ounce in 2013.
Process Mining is a new, powerful tool for this "raw material utilization" and offers an innovative digital approach that combines data mining and process optimization. Supported by real data, it provides valuable, detailed insights into a company's decisionmaking processes and points out ways of .
Silver (and most other metals) react with the chlorine to form silver chloride as a slag on top. This process produces gold to a purity of %, which is usually cast directly into odd weight 400oz bars used in the wholesale markets.
Yet mining the ore is just one stage in a long and complex gold mining process. Long before any gold can be extracted, significant exploration and development needs to take place, both to determine, as accurately as possible, the size of the deposit as well as how to extract and process the ore efficiently, safely and responsibly.

Silver is removed by the Parkes process, which consists of adding zinc to the molten lead bullion. Zinc reacts rapidly and completely with gold and silver, forming very .
At the surface, the ore is subjected to additional crushing and fine grinding. A flotation process is used to separate the silverbearing galena and tetrahedrite from other ore minerals and waste rock particles (tailings) to form mineral concentrates. Development of the flotation process occurred in the early days of mining at Broken Hill.
Process mining is not another wave. It is a tsunami. It is so big that the Financial Times predicts it will be a concept as common as the industry Last, but not least, Markets and Markets predicts that the process mining industry wil be worth over by 2023.
The Copper Mining Process. Once it's located within the earth, copper ore goes through eight stages before the consumer sees it in various products that affect every day life in the home and business. These eight stages include: Mining; Grinding; Concentrating; Roasting; Smelting; Conversion; Anode Casting; ElectroRefining
Mining technology consists of the tools, methods, and knowledge used to locate, extract, and process mineral and metal deposits in the earth. The methods used to locate ore bodies range from ontheground reconnaissance by prospectors to remote sensing techniques such as satellite imagery.
Jun 29, 2017· The most important factors to consider when selecting a gold/silver mining risk plays such a pivotal role in analyzing gold/silver mining stocks.
The key to effective process management is processtransparency which allows you to monitor and improve your existing processes. And that's where process mining comes in. Process mining is a data driven technique that enables you to analyze your process steps as they are executed in reallife.
In the United States, mercury mining has also stopped, although small quantities of mercury are recovered as part of the gold refining process to avoid environmental contamination. China, Russia (formerly the USSR), Mexico, and Algeria were the largest producers of mercury in 1992.
Process mining is a promising tool that is useful at different stages of the audit process, especially tests of internal controls. The data stored in event logs provides auditors with abundant information that could serve as additional audit evidence when performing tests of controls or other audit procedures. In addition, event logs are ...
Each process relies on the initial grinding of the gold ore, and more than one process may be used on the same batch of gold ore. Mining 1 In lode or vein deposits, the gold is mixed with another mineral, often quartz, in a vein that has filled a split in the surrounding rocks.
Dec 28, 2011· A flotation process separates silverbearing galena from waste rock particles called tailings. The flotation process was developed in the 19th century and is still used today, with many improvements over time. The process involves mixing the groundup ore, water and chemicals, which are then agitated in the flotation cells.
Processmining analysis related with business intelligence, is a new idea in the science of data mining. This analysis is made by using event logs and it provides a knowledge about a general process.
Process mining is an innovative approach and builds a bridge between data mining and business process management. Process mining evolved in the context of analyzing software engineering processes by Cook and Wolf in the late 1990s. Agrawal and Gunopulos and Herbst and Karagiannis introduced process mining to the context of workflow management.
The leaching process in mining is carried out either as heap leaching or insitu leaching. Precious metals such as gold are extracted from their ores by a cyanide or ozone leaching process. Radioactive metals, such as uranium are extracted by the process of acid leaching.
