Serpentine leafminer
Leaf mines are typically serpentine or irregular in shape and increase as the larvae mature. Mining activity by the larvae causes loss of healthy leaf tissue, affecting the plants ability to photosynthesize. The damage caused when the fly lays its eggs, or during the mining process of the larvae, can lead to diseases caused by fungi and bacteria.

An innovative process for magnesium production
The Magnola process produces magnesium metal using serpentine tailings as the raw material source. These mining residues, containing up to 24% by wt Mg, have accumulated over decades of mining the serpentine ore for asbestos fibres. The tailings are leached with HCl, then neutralised to separate the Si/Fe leach cake residue.
