Sovereign Metals: 99.9995% Purity Graphite Confirms Suitability for Multiple Downstream Applications

(firmenpresse) - Sovereign Metals: 99.9995% Purity Graphite Confirms Suitability for Multiple Downstream Applications

Sovereign Metals Limited (the Company or Sovereign) is very pleased to announce that downstream application test work has produced ultra-high purity levels of 99.9995 weight % C from its Malingunde natural crystalline flake graphite. The purification process utilises a simple high temperature process, which as a result of inherent uniqueness of the Malingunde flake graphite, requires low energy input to efficiently achieve some of the highest purity graphite in the world.

Sovereign has demonstrated the ability to produce a range of premium-quality products providing the potential to generate revenues from sales of premium priced flake graphite products to end-users in both traditional and emerging markets.

Ultra-high purity graphite is used in downstream applications which require strict control over impurities in the material, such as the production of semiconductors and photovoltaics for industries which include lithium-ion batteries, aerospace, electronics and nuclear energy.

HIGHLIGHTS:

- Ultra-high purity 5-Nines 99.9995 weight % C graphite (by LOI analysis) produced via non-acid leach technique.
- Test work undertaken using proprietary thermal purification process conducted at reduced temperature, requiring lower energy input and therefore having a significantly reduced CO2 footprint compared to other thermal technologies.
- Extremely low content of total impurities of less than 5 ppm against generally accepted maximum of 490 ppm for most advanced battery applications.
- Thermal purification is far more environmentally friendly than the incumbent commercial method which uses hydrofluoric acid.

Figure 1. Graphite market sectors and Malingunde product types and market suitability.

The Company is undertaking further downstream test work to demonstrate the suitability of Malingunde concentrates for a range of end-user applications, including the optimisation of spherical graphite production, with results to be released to the market in the coming weeks.

Sovereigns Managing Director Dr Julian Stephens commented, Achieving 5-Nines purity in a simple and cost-efficient manner is a very important milestone in enabling entry into the emerging Li-ion battery sector and other value-add markets. Entry to emerging markets, combined with sales to high-volume, high-value, traditional markets such as refractories, foundries and other industrial applications provides Sovereign with unique product marketing optionality and the potential to sell Malingunde concentrates to a wide range of customers.

INTRODUCTION

Sovereign is undertaking a comprehensive test-work program at a renowned, North American ISO-compliant private graphite technology laboratory (GTL) to assess the suitability of mine gate graphite concentrates from its Malingunde saprolite-hosted graphite project to various high-end industries and applications. The test-work program covered in this announcement involves the following work streams:

1. Assessment of the raw flake concentrate in terms of flake size, thickness, overall chemistry and other important physical properties.
2. Purification of the raw concentrate using proprietary, lower temperature thermal techniques with addition of low levels of halogen gas.
3. Assessment of the various physico-chemical properties of the resultant purified graphite product.

RAW CONCENTRATE PROPERTIES

The raw graphite concentrate used in this downstream testwork program was generated from scrubber and flotation metallurgical testwork previously reported on 29th May 2018. The prior testwork had confirmed the very robust metallurgical characteristics of the Malingunde saprolitic material (saprolite and saprock) and very good amenability to produce high grade, coarse flake graphite products with standard mineral processing technologies. Final concentrates from the prior metallurgical testwork averaged approximately 60% weight in the +150 µm fractions with graphitic carbon content in the 96 wt% to 98 wt% range. LOI tests conducted at GTL in the United States have independently confirmed these findings by reporting the concentrate purity in the range from 97.72 to 98.04 and the average of 97.94 wt%C.

Various physical properties of the raw concentrate were tested by GTL as a baseline measurement for later comparison with the purified samples. This highlights that Sovereigns raw concentrate has a very significant percentage of large and jumbo flake; a prerequisite for segmenting Sovereigns targeted graphite output and serving a variety of value-added markets from refractories to crucibles and expandable to advanced battery systems.

Importantly, scanning electron micrograph (SEM) imagery shows significant flake thickness, with some flakes in the +700µm category as thick as 50µm, which alone identifies them as a very unique source. The SEM data also revealed that the flakes are not intercalated with gangue minerals and any impurities appear to sit on the surfaces as opposed to being intercalated within the flake structure. This is very important for value-added processing because impurities that pepper the surface are typically much easier to remove than those appearing as gangue embedded into the flake structure.

It was also noted that stacks of graphene layers are somewhat primed open whilst remaining parallel to each other. Such particle deportment is rare and assists the thermal purification process.

THERMAL PURIFICATION

A sample of Malingunde raw graphite concentrate (mine gate product) was purified using a GTL proprietary low temperature thermal purification process. Low temperature is defined as a process that runs at less than 2,100°C and is facilitated with very mild addition of chlorine gas. The majority of thermal purification processes in the graphite industry sector are performed at temperatures of 2,700°C to 3,000°C, which require very high energy input and add significant costs, as well as generate a notably higher CO2 footprint.

The dwell time and the flow rate of chlorine gas used were designed to purify the graphite to 3-Nines 99.98 wt%C. However, when flake was removed from the furnace and recharacterized it showed a purity level of 99.9995 wt%C, equating to just ~5 ppm of total impurities (Table 1), highlighting the ease in purification of Malingunde flake due to the suite of unique material properties characteristic to Malingunde graphite deposit.

PHYSICO-CHEMICAL PROPERTIES OF PURIFIED GRAPHITE

After purification, the impurity concentration in the concentrate was reduced to less than 5 ppm (Table 1). The generally accepted maximum impurity concentration for advanced batteries is 490 ppm total and 170 ppm for the sum of critical element concentration (Nardi 1998).

As this material has under 5 ppm total impurities, and even lower levels of critical battery system impurities, it exceeds the referred standards by orders of magnitude in purity.

Additionally, the Malingunde ultra-high purity graphite surpasses the 2 ppm maximum boron concentration and 99.995 wt % C (4-Nines) thresholds which define nuclear-grade graphite purity standard (D7219-08, Standard Specification for Isotropic and Near-isotropic Nuclear Graphites) of ASTM International.

POTENTIAL MARKETS

The exceptionally high carbon purity and very low levels of critical impurities indicate that this material meets prerequisites for commercialization in the value-added marketspace. One of the targeted market uses of the flake is the advanced Li-ion battery sector. Standard Li-ion battery anodes are currently >99.95 wt%C, so Sovereigns purified material could lead to superior electrochemical performance.

Another major market for ultra-high purity graphite is in nuclear science, namely for pebble bed modular reactors.

CONCLUSION AND NEXT STEPS

Sovereign has been able to achieve a 5-Nines graphite product via a relatively simple process. This is a very important milestone as it highlights the potential for Sovereign to enter the high-end Li-ion battery sector as well as high-tech and specialty markets including the nuclear sector. Entry to emerging markets, combined with sales to high-volume, high-value, traditional markets such as refractories, foundries and other industrial applications, provides Sovereign with unique product marketing optionality and the potential to sell Malingunde concentrates to a wide range of customers in a variety of industrial sectors.
The next steps in the downstream processing will focus on milling and classification of the purified flake into spheronised graphite products for Li-ion battery anodes and other high-end electrical and electrochemical applications. This will be followed by electrochemical cell testing to examine the purified, spheronised materials performance (i.e. reversible, irreversible capacity and irreversible capacity loss, etc.).

FurtheThe nature and The company is currently completing a
r scale of pre-feasibility study. The next phase
work planned further of work is planned to be a definitive
work (e.g. test feasibility study. The next steps in
for lateral the downstream processing will focus
extensions or on milling and classification of the
depth purified flake into
extensions or
large-scale spheronised graphite products for
step-out Li-ion battery anodes and other
drilling). high-end electrical and
electrochemical applications. This
will be followed by electrochemical
cell testing to examine the purified,

spheronised materials performance
(i.e. reversible, irreversible
capacity and irreversible capacity
