Rhosonics SDMs win plaudits at OCP Group’s Beni Amir phosphate mine

Rhosonics Slurry Density Meter (SDM) has proven its worth at the OCP Group’s Beni Amir phosphate mine and washing plant in Morocco, the Netherlands-based company said in its latest case study.

The leading phosphate miner recently evaluated nine months’ worth of test work at Beni Amir, which came out with favourable results.

OCP began operating the Beni Amir mine and washing plant in Morocco in 2015. Here, the phosphate ore at the washing plant goes through a wet treatment process to enrich the ore and increase its “Boone Phosphate of Line” content, according to Rhosonics.

Four pieces of the Rhosonics SDM, a non-nuclear density meter using sustainable ultrasonic technology, were installed at the Beni Amir plant in April 2018.

Rhosonics said: “The phosphate industry traditionally uses nuclear devices. Non-nuclear devices are still quite new to this industry and success stories are limited.”

By measuring the acoustic impedance of a slurry, the SDM calculates the density of the slurry in-line during the process, according to Rhosconics. The sensor is made of stainless steel and ceramic material. “Because of the new sensor material, the sensor has lots of better properties. By making use of ceramic material, the ultrasonic signal is more bright and powerful than before.”

Mohammed el Moudden, Chief Instrumentation of OCP Beni Amir, said: “We confirm a successful test of the SDM from April 2018 until now. A single calibration is sufficient for operation over three months. The team at the Beni Amir washing plant are satisfied with this technology.”

The Rhosonics SDMs were installed in the output of a cyclone, a mixing tank and two thickeners to improve the efficiency and fully use the production capacity of these separation processes, Rhosonics said.

Now, following this trial, the OCP Group has bought 13 additional non-nuclear Rhosonics SDMs to install at several locations at the washing plant, the company said.

Mosaic clears final hurdle to develop Ona phosphate project in Florida, US

The Mosaic Company has acquired the US Army Corps of Engineers 404 permit for its Ona phosphate project in Hardee County, Florida. This was the final remaining permit for the project and secures 160.2 million tons, or 145.33 Mt (metric), of phosphate rock for future mining, the company said.

The overall project covers 22,483 acres (9,099 ha) with 16,778 acres of land permitted for mining.

“The western extent of the project will extend the life of Mosaic’s Four Corners mine by 14 years, while the eastern extent will provide mining for future decades at the South Pasture mine once production resumes at that facility,” the company said.

Mosaic President and CEO, Joc O’Rourke, said: “This important project helps secure the continued operation of our Florida manufacturing facilities. It will deliver tremendous value to the local community, our employees and our investors well into the future.”

Permitting efforts for the Ona project began in 2011. Mining permits from the State of Florida were issued in 2015 and local government permits were secured in July 2018.

Fluor completed the front-end engineering and design scopes for the Ona project, which includes an expansion of the existing South Pasture beneficiation plant, an extension of the life of the existing Four Corners beneficiation plant, and installation of a 24 km mining access/pipeline corridor.

Late last month, Mosaic reached a major milestone in the development of its multi-year mine project at Esterhazy K3, in Saskatchewan, Canada, with the commissioning of the production hoist and sending of the first bucket of potash on the overland conveyor to the Esterhazy K2 mill.

The commissioning of the K3 production hoist, which will move 60-ton skips, takes the company one step closer to mitigating Esterhazy’s brine inflow costs and risk, it said. K3 is expected to reach full operational capacity by 2024.

Alliance and Incitec Pivot extend FIFO contract at Phosphate Hill

Mine and plant workers will continue to have a fly in/fly out (FIFO) option at the Phosphate Hill operations in northwest Queensland, Australia, after Alliance Aviation extended its air charter services contract with owner Incitec Pivot.

The contract has been extended for three years with a bolt on two-year option that could see the service continue until 2021.

Incitec Pivot expects to produce 880,000 tonnes of ammonium phosphates from the operation in the year to the end of September, below the 975,000 tonne per year capacity. Phosphate Hill consists of its own mine and ore processing facility, in addition to beneficiation, ammonia, phosphoric acid and granulation plants.

Alliance has been providing air charter services to Phosphate Hill, 1,000 km from Townsville, since 2002. It provides these from its Townsville and Brisbane bases.

Lee Schofield, Alliance’s Chief Executive Officer, said: “Flying into Phosphate Hill commenced in 2002 – the same year in which Alliance was established – and we are delighted to have retained this foundation contract for a further five years. By the conclusion of this new contract, Alliance will have been flying into Phosphate Hill for a continuous period of 19 years.”
