METHODS, DEVICES, SYSTEMS AND PROCESSES FOR UPGRADING IRON OXIDE CONCENTRATES USING REVERSE FLOTATION OF SILICA AT A NATURAL pH

Cationic reverse flotation methods, systems, and processes for producing a marketable iron oxide concentrate from an iron oxide mineral slurry (treatment slurry), wherein the iron oxide content of the concentrate is greater than the iron oxide content of the treatment slurry, include introducing the treatment slurry into a flotation cell, together with a collector, a frother and optionally an iron oxide depressant, and recovering two flow streams from the flotation cell, namely a froth fraction (also referred to as a flotation tail fraction) and a sink material fraction (also referred to as the flotation concentrate), wherein the treatment slurry in the flotation cell is maintained at a Natural pH.

The present disclosure provides an exemplary process for a system that may remove particulate from industrial fluids using a Particulate Removal System (PRS). In some aspects, this system may treat water pulled from different Industrial Fluid Systems (IFS) while doing continuous monitoring and quality tests of the water. In some embodiments, the system may use sensors and other technology to allow for the system to periodically self-clean itself allowing for maximum efficiency and accuracy while also cleaning the water from the IFS. In some implementations, the water from the IFS may be separated through a Particulate Trap Mechanism (PTM) to ensure that particulate including dissolved material has been removed from the water and separated from possible contamination throughout the system. In some aspects the system may be used for continuous and direct measurement of water quality and automatic chemical level adjustment by systems to maintain a desired range or setpoints.

WASTEWATER TREATMENT SYSTEM AND METHODS UTILIZING CHEMICAL PRE-TREATMENT AND FOAM FRACTIONATION
20250270114 · 2025-08-28 ·

A two-step process for recovering useable solids from food processing wastewater and for significantly reducing the pollutants, chemical, bacterial, and viral load. The first step is the addition of pretreatment chemicals such as metal-based coagulant, pH adjuster, oxidant or a combination thereof. The second step is pumping the chemically pretreated wastewater into a foam fractionation system where a gas is introduced into the chemically treated wastewater to create a rising foam that captures and remove solid materials from the remaining wastewater effluent. The solids are recovered for additional post-processing and the effluent is discharged for post-processing or to existing bodies of water.
