How to increase diamond recovery using froth separation?

A new study reveals innovative methods to improve the efficiency of froth separation for diamond-bearing kimberlites. Researchers have proposed solutions that could reduce diamond losses by up to 20%!

🔹 Key Findings:
1. Restoring diamond hydrophobicity by removing mineral coatings through combined treatment: thermal, ultrasonic, electrochemical, and reagent conditioning.
2. Optimal temperature regime:
- heating the feed to 85–90°C for preparation;
- conditioning at 30–40°C;
- separation at 20–24°C.
3. Collector optimization:
- adding low- and medium-molecular fractions increases collector efficiency by 16%;
- ketone additives enhance adhesion activity up to 87%.
4. Closed-loop water recycling with clarification reduces reagent consumption by 8% without compromising concentrate quality.

Although some channels have been removed, the curation process is considered opaque and insufficient by analysts. There was another possible development: Reuters also reported that Ukraine said that Belarus could soon join the invasion of Ukraine. However, the AFP, citing a Pentagon official, said the U.S. hasn’t yet seen evidence that Belarusian troops are in Ukraine. This provided opportunity to their linked entities to offload their shares at higher prices and make significant profits at the cost of unsuspecting retail investors. To that end, when files are actively downloading, a new icon now appears in the Search bar that users can tap to view and manage downloads, pause and resume all downloads or just individual items, and select one to increase its priority or view it in a chat. As a result, the pandemic saw many newcomers to Telegram, including prominent anti-vaccine activists who used the app's hands-off approach to share false information on shots, a study from the Institute for Strategic Dialogue shows.
