Pilot testing and

process validation

Test an idea, validate a flowsheet, de-risk an investment. Loophouse takes chemistry from grams to 50 kg/h continuous, with an analytical laboratory on site and every run evaluated in full, mass balance included.

Your campaign is run by people who have built and run commercial scale plants.

Simulation first, testing second

Every campaign starts in our simulation and AI tools before anything enters the lab.

Unit Operations

Hydrometallurgy, pyrometallurgy, and crushing and sorting, fully equipped at lab and pilot scale, with an analytical laboratory on site. A full flowsheet runs end to end without leaving the building.

Weeks, not quarters

Loophouse holds every unit operation a campaign needs under one roof, so nothing is outsourced and nothing waits. The QC laboratory sits next to the pilot hall: results from a day of operation are available by the end of that same day, and the next run is corrected and planned on data instead of waiting on an external lab. That loop, an experienced team, and a facility designed for turnaround are why campaigns start in weeks and runs iterate daily.

Beyond piloting

Process development, optimization, flowsheet development and simulation, engineering studies covering design basis and criteria, mass and energy balances, and equipment specification, and technical advisory on scale up, fast commissioning, and ramp up. If it involves getting metal out of a complex stream, we have probably run it. A campaign runs from scoping, covering feedstock characterization, target product definition, and simulation of the full flowsheet, through bench trials at gram to kilogram scale to lock the process window, into pilot runs at up to 50 kg/h continuous with real time control, and out as an engineering package: developed flowsheet, mass balance, product samples and analysis, process design basis and design criteria, and the selection of equipment and technology for each unit operation.
