• The DH Process offers higher on-stream times which results in higher annual production capacity and reduced maintenance (reduced OPEX).
• DH Plants operate at a lower temperature which reduces the problems with rubber lining and corrosion allowing a lower grade of stainless steel (reduced CAPEX).
• The DH Process is more forgiving to variations in rock quality, which offers flexibility to accept different rock qualities. Especially for producers who import rock phosphate.

• The DH Process generally requires smaller filters due to the higher filtrations rates (reduced CAPEX).
• The DH Process does not require dry rock nor anti-scaling agents (reduced CAPEX and OPEX).
• The DH Process results in the highest on-stream operating factors in the industry.
• Simplicity in design makes operations easier than other technologies.
• A properly designed DH plant will have the highest global recoveries of the other technologies.

The Hemi-Hydrate (HH) process is sometimes selected when the plant is located close to a mine owned by the operator and steam is costly (for example no adjacent sulfuric acid plant). It allows production of 38-48% P₂O₅ acid directly, with consequent valuable savings in energy. 

• The HH Process can accept coarse rock grind which reduces the overall power consumption associated with grinding (reduced CAPEX and OPEX).
• The HH Process produces 38-48% P2O5 acid directly from the filter which reduces the steam/water consumption associated with the evaporators (reduced OPEX).
• The HH Process requires less cooling which impacts the design of the flash cooler (reduced CAPEX) .
• No 40% acid clarification required (reduced OPEX). Acid from the HH process tends to contain substantially less free sulphate and suspended solids and lower levels of aluminum and fluorine.

Hemi-Hydrate (HH) is the second most used wet process after the Di-Hydrate (DH).

• The HDH Process produces 38-48% P2O5 acid directly from the filter which reduces the steam/water consumption associated.
• The HDH Process has a typical P2O5 recovery of 98.5% compared to 95% for DH and 92% for HH.
• The HDH Process can accept coarse rock grind which reduces the overall power consumption associated with grinding (reduced CAPEX and OPEX).
•  The HDH Process produces 38-48% P2O5 acid directly from the filter which reduces the steam/water consumption associated with the evaporators (reduced OPEX).
• The HDH Process requires less cooling which impacts the design of the flash cooler (reduced CAPEX) .

• No 40% acid clarification required (reduced OPEX). Acid from the HDH process tends to contain substantially less free sulphate and suspended solids and lower levels of fluorine.
• The HDH Process produces a significantly cleaner gypsum than the DH or HH processes.

The major feature of the JT process is the annular reactor.

• The reactor has many advantages versus other reactor configurations.
• Each reactor is custom built based on the ore source and process goals. Sturdy reinforced concrete construction with an inner support wall for proven long life.
• Circular with few dividing walls. The configuration minimizes downtime during normal maintenance clean outs and provides the highest on-stream factors in the industry.
• Agitators, rock feed, sulfuric, recycle feed and flash cooler feed generate recirculation while the agitators provide mixing and wall velocities to keep all solids entrained and minimize scaling. This keeps the total reaction volume available year-round.
• If an agitator fails and it must be removed for maintenance, the others keep the process going and a shutdown is not necessary.
• Agitation is optimized utilizing state of the art techniques which minimizes CAPEX/OPEX and maximizes dissolution, gas dispersion and internal recirculation.

• The reactor provides a controlled combination of slurry recirculation by means of cooler circulating pumps and back-mixing from the geometric configuration of the annular reactor. The combination provides the least capital and operating costs for obtaining a high yield and extremely filterable gypsum.
• Stable reaction system with very easy sulfate control. Variations in rock feed streams are easily handled.
• Proprietary mixing tee for sulfuric acid addition eliminating hyper- saturation zones producing a highly filterable gypsum.
• Rock dissolving area completely separated from the maturation area for crystal growth and desaturation.
• Defoamer consumption per ton P2O5 has been shown to be low at high throughputs.
• Low-level, low-energy flash coolers for process temperature control and slurry recirculation. Designs minimize entrainment and potential carryover and provide a means to recover any P2O5 lost through the vapor duct as well as removing silica from the system if that is a process goal.
