So if I'm reading this right Carbon Black Substitute was 1 of 3 carbon containing products being investigated as side revenue streams, the others being Ferrosilicon briquettes and carbon-silica fillers?
Am wondering to what extent these 3 impact each other if at all?
Could there be another 2 income streams about to drop?
"Ferrosilicon briquettes
The Company has tested the creation of briquettes from the whole tailings product (without concentration), and the use of those briquettes in smelting to make ferrosilicon. Ferrosilicon is usually made by smelting a mix of silica, obtained from mining, and carbon in various forms. The briquettes will substitute for the whole of the silica required, and part of the carbon. Test work showed that good quality ferrosilicon can be made from this material and study work is now in process to determine the likely size of the market, logistics requirements, product pricing and end use customers.
Carbon black
Carbon black is a high-value form of carbon, used in the making of rubber, particularly tyres. It is usually made by burning hydrocarbons in a depleted oxygen atmosphere. Early work determined that the tailings from the Company's production of vanadium, after concentration to around 40% carbon, has the potential to be used in partial substitution for carbon black in the making of rubber generally, but particularly in the making of tyre side walls, with the Company's product substituting for a part of the commercial grade of carbon black N660.
A test programme has demonstrated that a simple flotation method can be used to concentrate the carbon grade to the required 40%. Early test work on the use of the concentrate in making rubber has been encouraging, and a further comprehensive programme is being undertaken to determine the characteristics and performance of the resulting rubber in various formulations and at various rates of substitution, aiming to provide sufficient information to allow marketing of the product to begin.
The Company is working with the National Engineering Academy of the Republic of Kazakhstan on a technological project covering the industrial production and usage of carbon-silica fillers in the making of rubber. The aim of the project is to construct a pilot plant, substantially funded by government grants, on the Company's existing processing site to concentrate the Company's carbon tailings to provide over 10 tonnes of carbon-silica concentrate per month for testing and marketing. Although the exact timing is not currently known, the expectation is that construction of the new pilot plant will be completed around the end of 2024 or early 2025, allowing test marketing and offtake negotiations for the product well in advance of the commissioning of the first Phase 1 module."
