Minjar Pajingo Gold Mine – Slurryflex Hoses for New Tailings Facility

Don’t let the last piece of piping in tailings process let you down.

Cracking and tearing is a common problem we see on tailings dropper lines.

It was something the project team at Minjar Gold’s Pajingo mine wanted to correct on the construction of their new tailings storage facility.

The team had previously used HDPE pipe to connect the ringline with the PVC dropper line, but they had problems with the rigid pipe cracking and tearing at the ring line join.

Dropper lines typically go up and over the embankment. Rigid piping – like HDPE – doesn’t sit flush with the wall and will crack and tear from the end pull of the slotted pipe. This leads to improper tailings placement.

That’s why we recommended flexible mining hose. It molds to the dam wall undulation. It’s also durable and easily copes with Pajingo’s corrosive, thick paste tailings.

Our Brisbane manufacturing team built 22, DN15 Slurryflex tailings dropper hoses with Victaulic spigot ends to connect to the ring line. The spigot ends prevent tearing due to the end pull on the other end of the hose.

We also split the delivery so there were no hold ups, and they could keep the installation crew onsite and the project on track.

It’s a simple, flexible, and long-lasting solution to a common issue with tailings dropper lines.
