Copper

Copper is a metal with high ductile and thermal conductivity. It has wide industrial use on a global scale and hence is of enormous economic value.  Copper can occur in metallic usable form in nature and is one the metals in that category. 

Its economic value stems from the proper predictability of its deposits and relatively consistent market price. That renders mining and processing more secure and justifies major investments. Copper is also relevant for small and medium sized operations if the grade is sufficient. In that case processing facilities with 10 ton per hour already generate substantial profits. 

Oftentimes, in case copper and gold occur in the same location, copper becomes the primary target while gold becomes a by product. That is due to the better predictability and capacity to generate continuous and steady cash-flow.

The extraction process is not overly complicated and adjustment to processing depend on the composition of ore. 

Medium scale miners should divert their attention to Copper instead of focusing solely on Gold. Just because copper has less value than Gold does not mean the cash-flow it generates is inferior. The opposite applies is many cases.

Copper Processing Methods

Pure Copper Plates

Copper processing depends on the ore type. In general the most common steps comprise:

1. Crushing
2. Milling
3. Pre Treatment
4. Flotation
5. Leaching
6. Solvent Extraction
7. Electro Winning

The result is a 99% pure copper plate ready for immediate sale on the market. 
  

Copper Concentrates

​Alternatively, the process could aim not to produce the 99% pure copper plates but concentrates. The concentrates have already economic value and can be sold on the market. In that case less of the value added chain is covered but aspects like budgetary or permit type related issue may require the concentrate production. 

The comparison of both scenarios is contextual and part of the initial consultancy to prepare the projects roadmap. 

SECA Approach

The following information is essentially required to set up a proper processing plant:

• the type of Copper
• its form
• its size and size distribution
• the total content
• the  comprehensive composition of material
• the elements that have potential to impact the processing system
• the way it liberates. 

Copper can be efficiently extracted once the information mentioned above is available. 
It is recommended to start out with the needed laboratory work and then proceed to a trial batch.
The trial batch processing is meant to test the theoretical assumptions in practice and proceed to actual production once the lab and trial work matches. This provide maximum security to the project owner and ensures optimally prepared production.
