摘要: An improved heap leach process for the bacterial heap leaching of base metal sulphide ores, the process including the addition of elemental sulphur to the ore, whereby sulphur oxidising bacteria indigenous to, or added to, the ore may oxidise the elemental sulphur and generate heat within the ore heap.

摘要: A smoke meter is particularly adapted to meter the smoke content of vehicle exhaust gases. The meter includes a measuring tube with a light at one end and a light detector at the other end, the amount of light detected corresponding to the smoke content. The optical surfaces are kept clean by inducing a flow of clean air across the surfaces using an air supply which also induces flow of gas into the measuring tube.
