Dissolving Ore?
Using only the HCl acid (muratic) will normally breakdown the rock/silca which encases the gold. but HCl is also used to remove/dissolve the base metals associated with plated gold. And then further refined by placing the gold recovered into a solution of HCl and bleach, which will dissolve the gold into the solution.

Recent exploration discovered two primary Au deposits, including Jiadi and Damaidi, hosted in the Emeishan basalt in southwestern Guizhou Province (Fig. 1), although a few small oxidized Au deposits were discovered and mined in this district since 1990′s.The two deposits are described as exhibiting some characteristics typical of …
Gold in Granite & Plutonic Rocks
The pyrite contains the gold. In the gold-bearing region of Northern Sonora, Mexico, the gold-veins are chiefly in or closely associated with granitic and plutonic rocks. The veins of El Grupo concession, about 100 miles southeast of Tucson, Arizona, traverse a fine-grained granite, and hear both gold and silver.
Basalt – Minecraft Wiki
Trivia. Geologically, basalt is a volcanic rock that cools from mafic lava flows. Mafic lava is runny, much like Nether lava, and under the right conditions it can cool into the stacks of basalt columns seen in basalt deltas . Basalt makes up most of Earth's sea floor, as well as Iceland and the Hawaiian Islands.

Mineral Resources in Jordan Introduction Metallic Ores
Location. The North Arabian Plateau Basalt covers an area of about 11,000km2 in northeast of Jordan and extends northwest into Syria and southeast into Saudi Arabia. Phillipsite, chabazite and faujasite are the most abundant zeolite minerals found in the Jordanian zeolitic tuff. The zeolite content in these tuffs varies from (20% to 65%).
A systematic review of sustainable gold extraction from raw ores …
In the context of its processing, gold deposits are typically classified, for the purposes of simplification, as: 1) free milling, and 2) refractory ores (including complex and carbonaceous). Based on their mineralogical characteristics and their mineral processing techniques required to liberate them, however, gold ores can be classified further.
Geometallurgy of cobalt ores: A review
Due to its low concentration in ores, cobalt is usually considered to be a companion metal which is of limited economic interest. The bulk of global cobalt production emanates as a by-product of extraction of commodities such as copper (~55%), nickel (~35%), and arsenic (Azevedo et al., 2018, Smith, 2001).The only exceptions, which …
