Cyanide and glycine leaching leader, Draslovka, looks to bring caustic soda production in house

Draslovka a.s. says it is in advanced discussions with technology-driven producers of caustic and chlor-alkali derivatives, including spolchemie, and several other international businesses with an aim of partnering with a producer to build a production facility at the company’s existing site in Memphis, Tennessee, using existing plant infrastructure.

The facility will apply the latest global production technologies to capture sustainability and economic benefits for all stakeholders, according to Draslovka.

Caustic soda is used in the production of Glycine Leaching Technology (GLT), Draslovka’s proprietary innovative leaching solution that, it says, offers substantive cost and sustainability benefits in the process of leaching metals from certain ores (including gold, nickel, cobalt and copper). Caustic soda is also used to produce sodium cyanide, used by the majority of the gold industry for processing.

By building and operating a caustic soda facility in partnership with an internationally-recognised specialist partner in the chlor-alkali value chain, Draslovka seeks to produce caustic soda in the most financially and energy-efficient manner to secure significant sustainability benefits compared with a number of current legacy producers, it says. As the market dynamics of caustic soda pricing can be volatile and US-sourced caustic soda is significantly more expensive than caustic soda from Asia and Australia, the move will allow Draslovka to significantly reduce its costs and improve competitive power. Own production will also give the company enhanced control of its supply chain.

The discussions with partners on expanding into caustic soda production and the chlor-alkali value chain are in line with Draslovka’s strategy of expansion and investment in sustainable processes and solutions, it says. The Memphis plant produces the majority of Draslovka’s mining solutions products and near-term production of GLT is being considered.

Pavel Bruzek, Chief Executive Officer of Draslovka, said: “These discussions are in line with our strategy of offering high-quality, cost-effective and sustainable mining solutions to our valued customers. We always strive to find the most economic supply of ingredients, hence we have begun discussions with several caustic soda manufacturers to partner and produce this integral ingredient. Own production will be a buffer against the macro factors of today, such as geopolitics, inflation and supply chain bottlenecks, as well as the fundamental disconnect between the US and the rest of the world’s caustic soda pricing. Our clients will have peace of mind they are accessing the full range of our sodium cyanide, GLT solutions and other mining products in a timely manner and at advantageous market prices.”

James Stockbridge, Director of Mining Process Solutions, Draslovka, said: “I am excited that the Memphis plant is being considered for the expansion into the production of caustic soda. Caustic soda price in the US is creating major headwinds to our competitive power in the international markets. Draslovka has invested heavily in the technology and process improvement at the Memphis facility since acquiring it in 2021 and we are committed to the area and our community in Memphis. We have a proud history and expertise, and the additional new facilities will allow us to expand our pool of local staff and affirm our leading position in the local business community.”

Draslovka about to move into glycine leaching mining demonstration phase

Czech Republic-based Draslovka Holding is heading into a busy 12-month period where its glycine leaching technology will be showcased at numerous mining projects across the globe, the company told IM on the side lines of the Resourcing Tomorrow conference, in London, this week.

According to Ivor Bryan, Director of Mining Innovation at Draslovka Mining Solutions and the former MD of Mining & Process Solutions (MPS), the entity responsible for the development of the GlyCat™ and GlyLeach™ technologies, the company is embarking on around 10 projects in the mining space, which will prove up the 3,500 hours of testing that has been conducted at MPS’ facilities in Perth, Western Australia.

MPS was acquired by Draslovka, a major sodium cyanide producer in 2022, with the aim of the transaction being to grow and develop the glycine leaching business.

Gold leach testing via GlyCat has been the major area of focus over the last decade. The process was invented to reduce cyanide consumption while maintaining gold recovery for gold ores from deposits containing nuisance copper. It has been designed to enhance the dissolution of gold and copper in gold/copper ores where glycine is used as a catalyst with cyanide in a cyanide-starved leaching environment. It doesn’t replace cyanide, but, in fact, enhances its leaching capabilities by dealing with the high-cyanide consuming copper within these gold-copper orebodies.

Yet, the company is also now starting to make inroads into the base metal space through GlyLeach, with nickel and cobalt two specific areas of interest. The technology is able to leach the targeted metals with enhanced selectivity compared with conventional methods. It will solubilise copper, nickel, cobalt and zinc, while gangue minerals such as iron, manganese, silicates and carbonates remain in the leach residue, Draslovka says.

This is allowing the company to promote that it can reduce the capital expenditure associated with processing these metals by removing the need for smelting, or in the case of tailings deposits, helping recover metal from assets previously written off as ‘waste’.

While the technology could have applications at run of mine operations, Bryan and his colleague Jackson Briggs, Corporate Development Manager of Draslovka, believe the most immediate opportunity is in tailings where the application of glycine leaching on ‘waste’ material could recover valuable metals while reducing the potential liabilities associated with such storage facilities.

Of the 10 or so projects the company has ahead of it, one is situated in Western Australia where the company is looking to recover nickel and cobalt metals from a tailings deposit of a major mining company.

Another project – much closer to fruition – is in Chile and involves leaching a carbonate-hosted copper oxide deposit containing some 600 t of material.

In both cases, the company is looking to demonstrate that it can recover valuable metals at high recovery rates, with low impact – namely rationalising reagent and water use and, in the case of nickel-cobalt, removing smelting from the equation.

This, according to Draslovka CEO, Pavel Bruzek, is a “win-win” for mining companies and their stakeholders, benefitting both the balance sheet and the operational environmental footprint.

“While we are a major sodium cyanide producer, when we saw the potential of MPS’ glycine leaching technology and the increase in metallurgical complexity of orebodies looking to be exploited, it made perfect sense to work with and promote this technology,” he told IM. “It is the responsible thing to do for the industry.”

Chemours offloads Mining Solutions business to Czech-based cyanide producer

The Chemours Company has entered into a definitive agreement to sell its Mining Solutions business for $520 million in cash to Draslovka Holding as, a Czech-based private company specialising in cyanide production.

The transaction is expected to close in the December quarter of 2021 subject to regulatory approvals and other customary closing conditions.

Chemours announced back in March that it had initiated a strategic review to assess the potential sale of its Mining Solutions business, which is a part of Chemours Chemical Solutions segment and is one of the largest North American producers of solid sodium cyanide.

Mark Newman, Chemours President and CEO, said: “Today’s announcement of the Mining Solutions divestiture furthers our strategy of focusing on our three principal businesses in order to drive long-term shareholder value. Leveraging differentiated strategies, we feel confident that our businesses are well positioned to deliver growth and higher-quality earnings through economic cycles.

“The entire Mining Solutions team has worked hard to create a leading business with an unmatched record of safety and supply chain stewardship. Draslovka’s long-standing expertise in cyanide, coupled with a strategy devoted to growing this business, makes them an ideal partner invested in the success of our Mining Solutions employees and customers.”

Pavel Brůžek, CEO of Draslovka, added: “The acquisition marks Draslovka’s first major investment in the US and advances Draslovka’s international expansion plans. Our ambition is to use Draslovka’s CN-based specialty chemicals expertise and technological capabilities to support our global growth plans, and drive improvements in safety, efficiency, and environmental considerations throughout the industry.”
