A complete range of single source solutions are available, designed and manufactured to the particular application, and use the most appropriate technology for the quality of feedwater to make it fit-for-purpose.

The solutions are designed in a modular format, and can be skid-mounted or containerized. Watercare mining do not have a standard solution range, which becomes restrictive, but prefer to design the plant specific to the client’s requirements.

Most plants are pressure tested on our site before shipping, and upon delivery to the client’s site, are commissioned to ensure that design specifications are met.

H | CoolQuench

A “point of use” chilled drinking-water unit, which processes feed water from underground mine-water or AMD (Acid mine drainage), and produces potable drinking water which is SANS 241 approved.

The unit combines various filtration media and Reverse Osmosis, together with a chiller to produce water to a cool 6 Degrees Celsius. If required a uranium extractor can be added to produce disinfected drinking-water.

Three standard sizes are available, which are a 200, 600 and 1200 liter per hour unit, and can sustain feed pressures from 8 to 16 bar, producing a 65 % recovery. Each unit is presented inside a specialized housing which makes for maximum portability and robust equipment protection, and is thus fit for underground use as well as surface applications.

A | De-Grit Plants

Grit is a major risk to sustainable and effective clarifier operations. Clarifiers are designed to remove silt at a size of below 75 microns. Grit can potentially block the underflow of a clarifier, and lead to the mud pumping system being damaged, resulting in loss of production and potential flooding.

Watercare mining has developed a de-gritting system that can effectively remove grit particles larger than 75 microns in size from a dirty water feed stream. The system consists of a stilling well, hydraulic separator and finally a classifying screw. The overflow from the hydraulic separator contains less than 75 microns silt which is fed to the clarifier. The underflow containing the grit is fed to a dewatering screw, with the grit being discharged into a dry ore handling system and transported to the surface process plant for further treatment.

Typical design parameters of a single system (Systems can be supplied in parallel to accommodate higher feed volume and grit loading):

Feed of 35 Mega Liters per day
Maximum amount of 12 ton per day grit
Below 5 kw installed power
95 % efficiency
Corrosion protected steel construction

B | High Rate Settler

Watercare mining used the combined experience gained over years of working on various clarifier systems to develop a unique clarifier that is revolutionizing dirty water handling systems. Our units have the smallest footprint per water volume treated, as a result of the high-rise rates achievable in the unique design. This results in major cost saving in underground excavations for new installations, and can also be retro-fitted into existing systems.

The unit has no moving parts that require regular maintenance, and is designed to allow for full maintenance access from the top of the individual reactors. These can be removed and maintained while the unit is on-line. The unit is robust in operation and stabilizes relatively fast after start up, thus minimizing solids carry over into clear water dams.

The units are structurally designed to withstand a total load density of 4.2 tons per cubic meter, thus eliminating any risk of a structural collapse in the event of a solids build up. 

Typical design parameters of a single system (Systems can be supplied
in parallel to accommodate higher feed volume):

100 litre per second feed rate
Small footprint, typically 9m²
Lower than 20 Parts Per Million in the clear water overflow.
Up to 40 m / hour rise rate
Modular design
Automated control of system

The unit can also be used in a thickening application.

C | BASK Belt Filter

The BASK belt filer is used for the screening and de-watering of any heterogenous water laden fines, but can be adapted for use in other mineral beneficiation processes.

The BASK belt filter differs from other methods through increasing the permeability and porosity of the material being treated by means of its unique, patented use of vacuum/ pneumatic agitation, hydraulic placement and mechanical handling of the product. This means that the screening efficiency is increased and de-watering efficiency improved.

Typical design parameters of a single system (Systems can be supplied in parallel to accommodate higher feed volume):

Modular design increases versatility of the system
Low capital and running costs
De-watering of + 75 microns material
20 % moisture content achievable under normal conditions
Feed flow rate of 75 m³ per hour at 30 % solids
Self-cleaning
Fully automated operation

SYSTEMS

Chemical Dosing Systems

Select Section: 

A | Lime Plant

Water infrastructure systems require the neutralization of acidic feed water to protect pumping infrastructure against corrosion. A controlled hydrated lime dosing system can even assist with suspended solid coagulation and dissolved heavy metal removal in settler systems.

The Watercare Mining lime dosing system is a simplified lime slurry mixing and dosing system designed into a compact, mobile plant. It eliminates the need for large lime mixing dams with expensive agitation systems. The plant consists of a dry material feed bin, screw feeder and a combined mixing and dosing pump.

The system operates by feeding lime at a variable rate into the mixing sump from where the dosing flow rate is constant. The feed is controlled by a variable speed drive linked to the pH meter to control the product loading into the system.

B | Flocculant Plant

Watercare mining has developed a series of automated flocculent make-up and dosing plants that cater for a wide range of applications in surface and underground applications.

Our plants are robustly designed to withstand the adverse operating conditions found in mining operations.

Our new generation flocculent plants make use of an automated flocculent make up system, which consists of a dry material hopper, screw feeder, two stirred mixing and hydration chambers as well as a dosing chamber.

The solution is prepared in batches and the system automation is based on a solid-state control philosophy.

C | Specialized dosing systems

A wide range of dosing and control systems are available for liquid and solid materials. The complete system including chemical tanks are placed in a variety of chemical-resistant portable HDPE bund-wall systems to contain spillages.

Remote Monitoring & Control

Watercare Mining is currently developing and rolling out a new information management system that will allow for comprehensive reporting and proactive management of our various activities. The goal is to gather and store all information in a central repository for which it can be accessed through various tools and platforms.

Our first comprehensive site monitoring system came live in late 2017, giving us the ability to remotely monitor our water purification plant at at a gold operation in South Africa. As the system evolves we will introduce the ability to remotely control plants (remote-SCADA), and allow automation of the plants systems through complex logic systems.

Once the system has completed the initial development phase, we will introduce a platform from which our clients will be able to view the performance of our plants over any internet connection.
