Ammonia Plant Design

The purpose of this study was to compare and assess process design options for the construction of a new 300,000 tonnes/yr ammonia plant with provision for future expansion to 450,000 tonnes/year. The ammonia had to be anhydrous (< 1 ppm H2O), contain < 2% of dissolved non-condensable gases, and be in a condition suitable for bulk transport off-site by road/rail links (which are available alongside the site). The new plant was to be located on a green-field site 5km east of the town of Sasolburg in the Orange Free State, South Africa. A recent government Environmental Impact Assessment has approved construction of the
new plant, with the following conditions:
(i) Atmospheric emissions will comply with current South African law, and will be subject to carbon tax
(ii) There will be zero liquid effluents, by use of lined evaporation ponds.

Reducing the carbon content in furnace copper concentrate by flotation

A global producer of copper and silver with an output of around 700 thousand tons of copper annually. The company have recently moved from shaft furnace technology to modern flash furnace technology. However, they have encountered major process problems with flash furnace heat load and urgently need to reduce the Organic Matter Content (OMC) of the furnace concentrate to avoid having to install an expensive roaster plant. The company have tried a variety of methods to achieve this, such as triboelectric separation & ore sorting, without much success. In July 2013, the company set-up a collaborative university competition (OMC challenge) to see if this problem could be solved innovatively. The aim of this project was to determine whether the carbon content of the furnace concentrate can be reduced from 9.5% to at least 7.0% using froth flotation. The project was conducted using laboratory mills and batch flotation cells in the Centre for Minerals Research. The project is a new area of froth flotation with significant future potential.
