The Response of Minerals in Laboratory Tests

Evidently, the behaviour of the mineral in the tests is an essential information.

The results of the tests confirm the first elections of the procedures or direct them differently.

Local Conditions

Multiple factors can intervene:

• Quantities of water available
• Distance from the bed
• Quality of the handwork
• Means of access
• Presence in the bed of gold in exploitation in proximity
• Climate
• Topography

Economic Conditions

• The price of gold
• Rhythm of exploitation, duration of the bed
• Costs of the reactives produced in the area

In the selection of a procedure, a succesion of alternatives is presented in each stage of the development of the project.

It could well be a little on the look of the inventive faculty, show the different possibilities which are offered for the development of a scheme of treatment.

Let it be understood that the election of one of the two terms of the different alternatives is not always evident.

The mineralogy of a mineral of gold is not presented in effect in a simple manner, a single manner. To the contrary, different forms of gold can coexist in the same mineral. Thus results the direct cyanidation can easily not be or good or bad, but will conduce only to the half results.

One must increase in each stage of following an economical appreciation including the technical appreciations.

We will precise, that the notion of exonerable gold used in this scheme must be taken in an extense sense, and is referred essentially to the possibility of exposition of the gold nuggets, to the lixiviating solutions of cyanide, after an eventual grinding.
