FLSmidth to provide gold processing package to Gold Fields’ Salares Norte

FLSmidth says it has sold three system packages to Gold Fields for its greenfield Salares Norte project in Chile.

The large downstream gold product line project comprises, FLSmidth says, three complete process islands: a Merrill Crowe, an AARL (Anglo American Research Laboratories) elution circuit and a refinery.

The process plant will treat 2 Mt/y of ore and is expected to produce an average of 2.6 Moz of silver and 286,000 oz of gold annually during its first seven years in operation, FLSmidth said.

FLSmidth’ s systems were chosen for their proven quality and the durability of the technologies involved, according to the OEM. “These factors were crucial for the customer given the modular, fully-automated and custom design required for the specificities of the gold mine, which is situated in the Atacama region of northern Chile at 4,500 m in elevation,” FLSmidth said. “Given the high altitude, it was important that the systems were as automated as possible, with the option of remote monitoring.”

The company added: “Salares Norte further solidifies our position as a premium supplier of projects and solutions even in the most challenging conditions. This contract is also noteworthy given how few new, large gold/silver mines have been established in South America in recent years. Supplying a significant portion of the flowsheet gives FLSmidth another strong reference with a major gold miner.”

Outotec and Metso have also won major orders for Salares Norte.

Jorge Carvajal, Project Sales Director, said: “These orders are the result of work well done and close collaboration. This, in conjunction with a strong focus on our customer during the entire process, were crucial in solidifying our position as a key technical solutions provider in the gold market.”

Ausenco to lead First Cobalt refinery restart study

First Cobalt Corp, following a finance agreement with Glencore, has started to award key contracts to complete a 55 t/d feasibility study on the proposed expansion of its cobalt refinery.

Field work is expected to commence in September and will culminate in the delivery of a definitive feasibility study (DFS) in the March quarter, the company said.

Ausenco Engineering Canada will lead the preparation of a DFS for a refinery restart at 55 t/d with SGS carrying out advanced metallurgical test work on cobalt hydroxide and a specialty cobalt feed to be supplied by Glencore, Knight Piésold conducting tailings studies in support of the DFS, Story Environmental taking on the environmental and permitting aspects of the engineering studies and Glencore providing technical support throughout the study phase through its Sudbury-based affiliate, XPS – Expert Process Solutions.

In addition to the delivery of the DFS on a 55 t/d refinery restart, a prefeasibility study (PFS) on a 12 t/d interim operating scenario will also be conducted.

First Cobalt recently announced it had entered into a $5 million loan facility with Glencore to complete advanced engineering, metallurgical testing, field work and permitting associated with a recommissioning and expansion of the refinery. Upon completion of a positive DFS for the expansion, and subject to certain other terms and conditions, Glencore is prepared to advance an additional $40 million to recommission and expand the refinery, according to First Cobalt.

Trent Mell, First Cobalt President & CEO, said: “The First Cobalt Refinery is a permitted facility that is in excellent condition and has a recent operating history. Our strategy is to work with Glencore to expand the refinery to serve the growing needs of the North American electric vehicle market. To that end, we have partnered with a first-rate study team appropriate for the importance of the task at hand.”
