The design of a full-scale industrial mineral leaching process

2001-1-1  The proposed design of a large-scale mineral-leaching operation is sketched schematically in Fig. 1, and was first suggested by Forbes .It consists of an array of vertical wells, spatially periodic in both the horizontal x and y directions, as shown. The wells thus form a square grid, with spacing 2S in both horizontal directions, and the z axis points vertically, in the opposite direction to ...

US3860289A - Process for leaching mineral values from ...

A process for leaching mineral values from an underground formation in situ, applicable particularly to uranium. In accordance with known practice, an aqueous solution of a leaching agent (alkaline or acid) is delivered into the formation, where it remains for a prolonged period, and then is pumped out with dissolved mineral values. Some minerals occur naturally in a relatively insoluble form ...

Leaching of minerals using sulfuric acid - reactionchamber

Sulfuric acid is considered a very strong and cheap acid. Most of it is used to break down minerals. This means the conversion of the generally very poorly soluble minerals into a substance from which the element or the desired compound can be more easily isolated. Extraction of raw titanium Titanium ores are primarily the Continue reading Leaching of minerals using sulfuric acid

What is leaching? National Critical Zone Observatory

2016-7-1  Leaching is not to be confused with the use of leeches as medicine. The word “leaching” is believed to have been derived from either late Middle English “leche” or Old English “leccan” meaning to moisten and to allow leaking. Currently, leaching primarily describes the process of water carrying soluble substances or small particles through soil or rock.
