The secondary uranium ore minerals have two major modes of occurrence: a) they occur in the weathered or oxidized zones of primary deposits where they are formed by the decomposition of primary minerals, and b) as irregular flatlying deposits in sedimentary rocks, primarily sandstones, also in conglomerates, shales and limestones formed by ...
In the case of diamonds, the kimberlite would be the primary source rock and the alluvial river gravels that contain the concentrated diamonds would host the secondary placer deposit. Gold originates from a primary hard rock source and is transported via rivers and streams.
This paper presents an overview of the various methodologies used in the recovery of gold from secondary sources. Gold recovery is interesting due to its vast industrial applications, high market prices and extensively used precious metal, the sanctuary value attributed to gold during international political and economical crises, and the limited resource of this metal may explain the recent ...

Oct 20, 2015· Placer Gold: The Stuff You Gold Pan For. To start off, there are two types of gold deposits: lode and placer. Typically, lode deposits are the traditional veins of ore that are embedded in rocks and minerals. To recover gold from lodes, miners have to blast, mill, or treat the rock with chemicals to recover the gold inside.
Supergene gold deposite are often classified as SECONDARY gold deposits. Other Secondary Gold Deposits are alluvial and eluvial gold deposits. Characteristics of Supergene deposits. There needs to be a primary gold source nearby at depth or up slope; High grade but small tonnage, with coarse gold and nuggets; Higher purity of the gold.
In ore deposit geology, hypogene processes occur deep below the earth''s surface, and tend to form deposits of primary minerals, as opposed to supergene processes that occur at or near the surface, and tend to form secondary minerals.
