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.

Right now the digital security needs of Russians and Ukrainians are very different, and they lead to very different caveats about how to mitigate the risks associated with using Telegram. For Ukrainians in Ukraine, whose physical safety is at risk because they are in a war zone, digital security is probably not their highest priority. They may value access to news and communication with their loved ones over making sure that all of their communications are encrypted in such a manner that they are indecipherable to Telegram, its employees, or governments with court orders. Just days after Russia invaded Ukraine, Durov wrote that Telegram was "increasingly becoming a source of unverified information," and he worried about the app being used to "incite ethnic hatred." On Feb. 27, however, he admitted from his Russian-language account that "Telegram channels are increasingly becoming a source of unverified information related to Ukrainian events." The message was not authentic, with the real Zelenskiy soon denying the claim on his official Telegram channel, but the incident highlighted a major problem: disinformation quickly spreads unchecked on the encrypted app. Meanwhile, a completely redesigned attachment menu appears when sending multiple photos or vides. Users can tap "X selected" (X being the number of items) at the top of the panel to preview how the album will look in the chat when it's sent, as well as rearrange or remove selected media.
