Ireco Chemicals, who hold the patents on the original slurry
formulations, and their licencees, sold approximately 26 m lbs
of small diameter (less than 2") slurries in 1977. This figure includes Iremite slurries in 1-11" dia at the rate of approximately 4,000 tons/annum for underground iron ore mining at Kiruna in North
Sweden and similar small diameter usages of more than 2,000 tons/
annum in Chile and Brazil for general purpose and underground
mining use.
ICI has full rights to the Ireco technology and intends to use this
in Hong Kong.
4 Two reports are attached which cover test programmes carried out
in Hong Kong with cartridged small diameter slurries.
These are:
1 Extract from Report on Trials with Iremite 60 slurry explosives
at Hitunnels JA Shaft.
Trials with Small Diameter Iremite Explosive, Hong Kong,
March/April 1977.
The quantities used in these test programmes were relatively small
and the remainder of the 70 tons supplied has been used successfully
in unsupervised trials.
