One of the most common words used in natural stone quarries is “recovery rate”. Yet when one explores further and speaks to industry people involved in the quarrying business, one finds what they all mean is not so easy to define. When people from different countries involved in quarrying are talking about recovery rate, they may actually be talking of very different things.

Over two years ago this magazine published a survey on multi-wire machines, and the article was well received by our readers. Being a new, evolving technology, during this period the different manufacturers have brought out new, improved models of this machinery, and we have found it appropriate to publish an updated version of the survey. The questions were sent to the different companies and we publish here the replies of those who answered them.
