Types Belt Conveyor
The type of belt conveyors are used to transport various materials over relatively short distances both horizontally and on an incline where the angle of the latter does not exceed 21° to 23° in exceptional cases. The material can be of almost any size and either dry or wet, but in the latter case the moisture content must […]

Ore Bucket Rail Car
Ore Bucket Rail Cars are built of the strongest welded steel design and are built with the expectation that continuous service will be required of them. As shown in the accompanying illustrations, these cars are made in two styles, both of which are built as standard units for eighteen gauge track. However, these ore bucket […]
Underground Mine Fire Prevention
During the winter and spring of 1917, an unprecedented number of underground fires occurred in the Butte district. With one exception, these fires were caused by the failure of electrical equipment, and called attention to the increased fire hazard in underground mining operations occasioned by the extensive use of electricity. Five local conditions that contributed […]
Solvent Extraction Training SX Course
Solvent extraction, the process of extracting a specific metal valve from a solution to concentrate and purify that metal is a multistage process involving liquid ion exchange. In the first stage the metal value, in this example copper, exists in the aqueous leachate as an copper ion. The aqueous leachate is mixed with a organic […]
Talc Grinding
The milling of talc, as is the case with many non-metallic minerals, until recently, has not received adequate technical consideration, for the talc industry has become of importance only within the last decade. At first, talc was used only in the massive form, for foot warmers, griddles, and so on, and milling methods were unnecessary. […]

LPF Process Metallurgical Testing
EXECUTIVE SUMMARY A Metallurgical Laboratory had completed preliminary economic studies on various processing options applicable to the Minerals Project in South America, containing oxide, transition and sulfide ore reserves. These included heap leaching with SX-EW; use of Roast-Leach-EW of sulfide concentrates to produce CuSO4 crystals; and potential application of the Leach-Precipitation-Flotation (LPF) option to treat […]
