Hi Sally
As I stated in my post neither plant would be in production until 2020 probably towards the end of the year.
As to compression well how long is a piece of string for the clave to be expedited. But the lead time is no problem with the HPAL circuit as there is massive amounts of prep work to do first. Site offices to be set-up, land to be cleared and levelled, underground services to be installed (sewerage,water,power), civils to be constructed ,which is all the grano work (concrete) for structures to be built on. Just in concrete work there is thousands of cubic metres of reinforced concrete to prepare and pour. The civils component of construction is the longest part of job.
The peripheral/associated part of the HPAL circuit can be built while waiting for claves. Just the refractory work in the flash tanks takes a few months to install and cure once flash tanks are built.
CLQ has as I already stated has a longer construction time due to the use of IX instead of CCD's. Also the added burden of having the huge associated Hydrochloric acid tanks that the IX columns use to flush and also the HCL reclaiming circuit, as the HCL can be reclaimed to save money on reagents. The sulphuric acid in HPAL cannot be reclaimed so is neutralized.
Once again there is not a hope in hell either plant will be ready before 2020.
