Metallurgical testwork, engineering, and EPCM for the global mining industry. From bench-scale through commissioning — all under one roof. Trusted by operators in 30+ countries since 1972.
KCA is the only mid-size mining EPCM firm with its own in-house metallurgical lab. We move your project from the first crushed sample through process design, fabrication, and commissioning — same team, same roof.
Column leach, BRT, CIL, CIP, HPGR, gravity, and Merrill-Crowe testwork in our Reno laboratory. 74+ projects per year, samples from 30+ countries since 1972.
Explore Lab Services →Scoping, PEA, PFS, feasibility, and full EPCM. 17 turn-key projects delivered. Detailed engineering for crushing, leaching, recovery, refining — on schedule, on budget.
Engineering Capabilities →74 modular plants delivered worldwide. ADR, Merrill-Crowe, modular labs, and carbon-converter systems — fabricated in the U.S., shipped and commissioned anywhere.
Plants & Equipment →EPCM delivery, construction supervision, commissioning, and operator training. From greenfield builds to brownfield expansions in every major mining jurisdiction.
Project Management →From 18,000 TPD heap leach in Zacatecas to a 13-month EPCM in Sonora — every project starts in our lab and finishes on a commissioned plant pad.
From the high Andes to the Sahara, from Turkey to Australia — we’ve delivered metallurgy, engineering, and EPCM on six continents.
KCA’s in-house lab made the difference. The flowsheet we tested at bench scale is the flowsheet that’s running on site today — with the recovery numbers to match. Same team from sample to commissioning.
We have used many EPCM firms over the years. KCA is the only one we trust with our full mine-to-metal scope. They deliver on schedule and the cost discipline is exactly what investors want to see.
The modular Merrill-Crowe plant arrived ready to bolt down. We poured first gold inside 90 days of receiving the skids. That kind of execution is rare and exactly what a remote project needs.
Testimonials representative of KCA client feedback. Specific clients identified upon request.
Most EPCM firms outsource testwork. We don't — which means your flowsheet is designed by the same team that builds the plant. One handoff. Fewer surprises. Predictable results.
Sample characterization, bottle rolls, column leach. The flowsheet is born here.
De-risk the design at scale. Validate recoveries, throughput, reagent consumption.
PEA, PFS, FS, detailed engineering. Capital estimates, schedule, risk register.
Build, install, commission, train. Pour first gold on the schedule we promised.
From majors to mid-tiers, our clients return because we deliver. Below is a partial list of companies that have engaged KCA for testwork, engineering, and EPCM — many on multiple projects.
From scoping studies through commissioning, KCA has delivered 500+ projects across six continents. Send us a quick note and we’ll respond within one business day.
KCA partners with affiliated offices on three continents to deliver projects where our clients operate. Same standards. Same engineering bench. Local presence.
