“…This diversity was highlighted by Mervine et al (2018) for kimberlites from different mines (Venetia, Gahcho Kué, Victor, Snap Lake) and from different lithofacies within a single mine or pipe. The mineralogical diversity of kimberlites from different locations in Russia (Archangelsk and Yakutia provinces) and China (Liaonin and Shandong provinces) has also been described by Posukhova et al (2013). In particular, these last authors were able to subdivide kimberlites into four main groups based on their mineralogy: (i) saponite-rich, (ii) serpentinerich, (iii) carbonate and phlogopite-rich and (iv) rocks with a complex mineralogical composition.…”

“…The source of Al 3+ to form chlorite and smectite is attributed by Stripp et al (2006) to alteration of plagioclase. Posukhova et al (2013) suggested that saponite is a pseudomorph of olivine in autolith breccias of the Archangelsk, Pionerskaya, Lomonosov and Karpinsky pipes in Russia. White et al (2012) also observed the partial or complete replacement of phlogopite by saponite.…”

Cation Exchange in Smectites as a New Approach to Mineral Carbonation

Mineral carbonation of alkaline mine residues is a carbon dioxide removal (CDR) strategy that can be employed by the mining industry. Here, we describe the mineralogy and reactivity of processed kimberlites and kimberlite ore from Venetia (South Africa) and Gahcho Kué (Canada) diamond mines, which are smectite-rich (2.3–44.1 wt.%). Whereas, serpentines, olivines, hydrotalcites and brucite have been traditionally used for mineral carbonation, little is known about the reactivity of smectites to CO2. The smectite from both mines is distributed as a fine-matrix and is saponite, Mx/mm+Mg3(AlxSi4−x)O10(OH)2·nH2O, where the layer charge deficiency is balanced by labile, hydrated interlayer cations (Mm+). A positive correlation between cation exchange capacity and saponite content indicates that smectite is the most reactive phase within these ultramafic rocks and that it can be used as a source of labile Mg2+ and Ca2+ for carbonation reactions. Our work shows that smectites provide the fast reactivity of kimberlite to CO2 in the absence of the highly reactive mineral brucite [Mg(OH)2]. It opens up the possibility of using other, previously inaccessible rock types for mineral carbonation including tailings from smectite-rich sediment-hosted metal deposits and oil sands tailings. We present a decision tree for accelerated mineral carbonation at mines based on this revised understanding of mineralogical controls on carbonation potential.

“…Modified saponite-containing product has been effectively used to produce high-quality ceramic bricks; the sample density amplified with the increase of sintering temperature: 1.9 ± 0.1 g/cm 3 (800 • C)-2.2 ± 0.2 g/cm 3 (1000 • C) [33]. Furthermore, the mineral has been reutilized from waste to pelletize iron-ore concentrates and produce high-quality building materials [34].…”

Approaches to reutilization of diamond clay tailings in northern environments are considered in the example of the Subarctic region of Russia. The monitoring studies are conducted at storage facilities of Severalmaz PJSC where ca. 14 million cubic meters of waste rock are produced annually after kimberlite mining and processing. The tailings of diamond ore dressing waste are situated in complex geological conditions of high-groundwater influx and harsh cold climate with low levels of solar radiation and the average annual temperature below freezing point. Furthermore, the adjoining protected forests with a significant diversity of biogeocenoses and salmon-spawning rivers are affected by the storage area. Reducing the impact of the tailings can be achieved through the reuse of the stored clay magnesia rocks obtained from saponite-containing suspension. The experiments reveal the most promising ways of their application as potential secondary mineral raw materials: cement clinker and ceramics manufacture, integration of alkaline clay into the reclamation of acidic peat bogs, and production of aqueous clay-based drilling fluid. Field and laboratory tests expose the advantages and prospects of each suggested treatment technique.

Methods of cleaning and processing of saponite-containing water from diamond processing plants in the Arkhangelsk region, Russia, are discussed. The advantages of electrochemical separation of saponite from process water enabling to change its structural-texture, physico-chemical and mechanical properties are demonstrated. Possible areas of saponite and modified-saponite products application are considered.
