This method submerges plant material in boiling water rather than direct steam. The process involves placing the plant material in a still and covering with water. As the water boils, the hot vapor passes through the plant material, extracting the essential oils. The vapor travels through a cooled condenser, allowing the oils to condense.

Chemical anal-ysis shows that most of the iron is concentrated in par-ticles of 160–2000 μm. The copper content in the frac-tions from 80–125 to more than 2000 μm varies from 0.5 to 0.3%1. In the <80 m fraction, ~1.5% copper is μ present. Accordingly, this fraction may be used as a recycled product.
