GoldGold is one of the most valuable previous metals and used as currency throughout history by mankind.
Its value and importance remains uncontested. In time of economic turmoil Gold constitutes the means to store value when paper money is not trusted. This function is unique to Gold. Other metals do not have this functionality, especially not throughout mankind's history up until today. That is the reason why it also is referred to as "Gods currency".
Sulphide GoldGold often occurres in combination with Pyrite, Copper and other minerals and the ore is Sulfide based. In that case the Gold is either fully (refractory) or partially (middling) encapsulated by other material which requires crushing and milling. The exact process depends on the particle size of the Gold. There are different processes for different particle sizes and conditions. The key is to adjust the processing method to match the Gold ores characteristics perfectly.

Free Gold
Free Gold is not attached to, entrapped in or combined with other rock and minerals but is already free and almost pure. That makes its recovery particularly efficient using gravity concentration methods. Depending in its geological position free gold is also referred to as placer, terrace, river or sea Gold. Free Gold comes in a variety of fineness grades ranging from large nuggets to very fine dustlike Gold.

Gold Processing MethodsSulfide based Gold Ores Bodies
Sulfide based ores are processed with the Xtriction system. The system comprises a range of different steps that need to be arranged and sequences based on the exact material composition. Such steps include for instance: Crushing, Milling, Regrinding, Conditioning, General and Specific Flotation, Ultra Flotation, Leaching CIL / CIP Carbonization, Smelting, Tailing Processing, ... The system is achieving maximum efficiency. A properly set up processing unit reaches an extraction efficiency of 98%. SECA specific methods like the Ultraflotation require much less space while processing the same or more quantities than ordinary flotation systems. The professional set up of processes and chemical agents and combinations requires extensive know-how and experience. Free Gold The plant is based on the size of Gold particles and its percentages per size level, its form and overall content. With such information the minimum economically viable operational scale becomes known and the system is built. Free Gold >0.08mm is extracted with the Xtradition system using various methods of gravity based concentration. Such concentration methods include screening, scrubbing / shredding, sluicing, subflow concentration, centrifugal concentration, magnetic concentration and smelting. The entire process is chemical free. In cases where a significant percentage of Gold particles are extremely fine additional modules are added to the process. Our expertise is ensuring that you do not need to worry about the extraction process. In the end, once set up and established, the system is easy to use for clients. Precision and extreme efficiency becomes a routine. |
SECA ApproachAll starts with knowledge. The essentials you need to know about your ore are:
The analyses needs to be conducted by certified and highly skilled experts. You can send material for such analyses either to us or an accredited laboratory specialized on mineral laboratory assessments. Before any major production plant is realized the laboratory data is complemented by actual batch testing in a pilot plant. Once the laboratory data matches the results for batch trials we can realize the final production plant. |
There are many things to know and consider. We understand that this can be confusing. Do not let this trouble and hinder you from starting your operations. The initial consultancy for orientation purposes is free and you are welcome to talk to us. Just leave your details and we get back to you within 24 hours.
We are only one call away.
