Mining
Nevada mines more gold than most countries. Moving ore, concentrate and process material means bags that survive abrasion, load and a long haul from a remote site — where a failed bag is not a quick resupply.
Nevada mining runs on material handling
Nevada is the centre of gold mining in the United States, and the operations here move enormous quantities of ore, concentrate and process material. Every one of those movements needs a container that matches the material.
Mining is unusually hard on bulk bags for three reasons at once: the material is abrasive, it is dense, and the sites are remote enough that a failure is expensive before anyone even counts the spilled product.
Where specification goes wrong
The most common error we see is sizing a bag by volume. Concentrate is heavy enough that a bag rated for a cubic yard of ordinary material is well past its safe working load before it is full. The bag looks like it has room left, so it gets filled — and the failure that follows looks like a defect rather than what it is.
Give us the material and the fill weight and that problem disappears at the quote stage.
