What CiDRA does

CiDRA Minerals Processing is a privately held US-based process optimization company headquartered in Wallingford, Connecticut. Founded in 1996, CiDRA develops and commercializes hardware-based measurement and separation technologies used by mining and mineral processing operators. Its product portfolio is anchored on three proprietary technology lines: SONARtrac passive-sonar flow meters for slurry pipelines, CYCLONEtrac real-time particle size sensors for hydrocyclones, and P29 engineered hydrophobic media for selective mineral separation. Together these systems allow operators to measure and control grinding, classification, and recovery circuits in real time rather than relying on offline sampling.

The company monetizes through engineered-to-order enterprise sales of hardware systems, accompanied by site-specific Front-End Engineering and Design (FEED) studies, installation, commissioning, and ongoing service. Pricing is quote-based and per-site, consistent with the large average contract values typical of mining capital equipment. CiDRA sells primarily to global mining majors and mid-tier operators, with named customers including OZ Minerals (Carrapateena copper-gold operation in Australia) and Rio Tinto (Kennecott). The commercial footprint extends to 718 mine sites across 73 countries. Go-to-market is a direct enterprise field-sales model, supplemented from 2025 onward by a strategic collaboration with mining-equipment OEM Weir Group, which provides global channel distribution. The company employs between 251 and 500 people.

In January 2021, the company spun out its concrete-systems business as CiDRA Concrete Systems with a strategic investment from Sika AG, allowing the parent to focus engineering and capital on minerals processing. CiDRA's underlying technology stack is hardware- and chemistry-centric — relying on acoustic physics, signal processing, and proprietary formulations — and the company has not disclosed material AI or machine-learning capabilities within its product lines.

Core offering

CiDRA designs, manufactures, and services proprietary hardware and process technologies for the global mining industry. Its core offerings are non-contact SONARtrac passive sonar flow and entrained air meters, CYCLONEtrac real-time individual hydrocyclone particle size tracking systems, and the P29 engineered hydrophobic media platform for coarse mineral separation (deployed as Grind Circuit Rougher or Rougher Pre-Cleaner applications). Products are sold to mining operators worldwide alongside FEED studies, commissioning, and technical services.

Product overview

CiDRA Minerals Processing offers a portfolio of hardware-based mineral processing optimization technologies. The core portfolio includes: (1) SONARtrac family of non-contact sonar-based flow and entrained air measurement systems (VF/GVF-200 digital, VF-50, PW VF-100, VF/GVF-100, HD VF/GVF-100) for volumetric flow measurement in mining slurries; (2) CYCLONEtrac classification optimization systems (PST for particle size tracking and OSM for oversize monitoring) providing real-time individual cyclone control; and (3) P29 Technology, a novel mineral separation platform using engineered hydrophobic media for coarse particle recovery up to 3mm, deployed as Grind Circuit Rougher or Rougher Pre-Cleaner applications. The company serves over 718 mine sites in 73 countries with measurement and control solutions.
