Diagonal Plane Shaking Table Design
Recent experiments indicate that the usual type of gold concentrating-table is not only poorly adapted to produce the desired results, but also is based upon an incorrect principle, namely, the use of riffles to perform the work of stratifying the various minerals. We have heard a good deal about riffles for concentrating-tables; exhaustive experiments have been […]
Fine Grinding in Cyanide Plant
This plant, near Marysville, Montana, was planned to treat the ore from the Piegan and Gloster mines, the latter being one of the early and famous producers of the Marysville district. When the mill was closed, treatment consisted of stamp milling, followed by pans and settlers for pan amalgamation. The extraction was evidently poor, because, a […]

Gold Room Security
Very little is documented about Gold Room Security due to the sensitivity of people around it. At the same time, when establishing a new operation it is useful to have a standard security starting point on which to address the issues with directly related to gold room security design fundamentals. This paper will provide guidelines and a ‘prompt’ […]
List Gold Metallurgical Tests
In order to have a preliminary idea about the metallurgical performance of the samples, some scoping tests have to be performed. They can be carried out in the prospective mine site and/or special metallurgical laboratory. The final election is based on the equipment availability and gold mineralization. Test to be done include; concentration by gravity, […]
Process Mineralogy
The treatment of auriferous ores presents several challenges to the metallurgists and plant operators due to there are some factors that have an important impact on the process. Without any doubt the mineralogy is the key aspect of the process performance. Basically, there are several options to be considered at the moment of evaluate the […]
Gold Extraction & Recovery Processes
Process Development Considering the different gold minerals present alone or combined with the host rock, it will be necessary to discharge the unwanted material in order to increase the concentration of gold in an economically manner. This part treats the strategy of beneficiation as a combination of several processes. Joining together these units make possible […]
Auriferous Deposits
Gold and elements of the platinum group metals have been found in several types of deposits around the world. Sometimes, deposits have been worked for their cobble and gravel components and these places have been set up to recover heavy minerals (mainly as black sands) from their host rock. These minerals carry precious metals and […]
Basic Gold Prospecting & Exploration Methods
Prospecting and exploration that is a search for precious metals deposits is not a simple process because big deposits were discovered a long time ago. There are several places with important content of precious metals waiting for skill prospectors. The large mining companies of the world are focused in big deposits and the small deposits […]
Gold Smelting & Refining Process
Gold can be concentrated and recovered by applying different gold refining process methods and the final product has variable quality. In this way, it is necessary to have a better marketable product so that the incomes can be improved. Then, we have two smelt and cast the gold into bars called bullion or Dore. The […]
