Grinding of leaves for extraction of nucleic acids

Cryogenic grinding is a very effective technique for taking hard substances, like plant and animal tissues, and turning them into dust. The tough carbohydrates of plant tissues become very fragile at -196°C and easily shatter. The two concerns with cryogenic grinding is that the sample may warm up, and secondly, throughput is very low.

Improvement of Silver Extraction by Ultrafine Grinding ...

Ultrafine grinding (UFG) was proposed as a pretreatment method prior to cyanide leaching of old plant tailings of a refractory silver ore. Direct cyanidation of the as-received tailings (d 80: 100 µm) led to a low silver extraction of only ≤43% over 24 h.A size-based diagnostic study has demonstrated that the refractoriness of the tailings is essentially physical in character.
