Trade-off Study and Logistical Analysis for Kachi Lithium Project

Lake Resources is an Australian mining company focused on the development of lithium projects. Lake’s flagship Kachi Project is located in the Puna region of the Catamarca Province, Argentina, within the well-known Lithium Triangle.

In November 2018, Lake announced a maiden JORC resource at Kachi of 4.4 million tonnes (Mt) of contained lithium carbonate equivalent (LCE), and an exploration target ranging between 8-17Mt of LCE. This ranks Kachi as one of the world’s top 10 brine resources.

Currently, Lake is involved in the development of a Feasibility Study (FS) for the project, and as part of this study, SAXUM developed a comprehensive logistic assessment regarding the construction and operational phases of the project/mine.

The objective of this logistic study is to provide relevant information, alternatives, and conclusions to Lake Resources for the Project Development and the Mine Operation that will allow them to determine the most convenient and cost-effective alternative and strategy for the import of main equipment during the construction phase of the project, as well as for the import, export and warehousing of reagents and final products during the plant operation.

SAXUM, through its team of experienced professionals in mining operations and logistics in Argentina, is performing this project within the highest quality standards.

Conceptual and Basic Engineering of two greenfield cement plants in Brazil - CSN

Companhia Siderúrgica Nacional (CSN) is a company that operates in five segments of the economy, Steel, Mining, Cement, Energy and Logistics. In 2009, CSN started producing Cement in Brazil. SAXUM has a long relationship with CSN and has participated in different projects, ranging from cement grinding to the new clinker and cement production line at Arcos.

On this occasion, CSN once again trusted SAXUM capabilities and services for the development of Conceptual and Basic Engineering and support for the EIA/RIMA regarding two greenfield cement plants in different regions of Brazil, with capacity of 4,500 and 7,200 tpd. The engineering services of SAXUM encompass all technical disciplines, from process and mechanical to civil/structural and electrical/instrumentation/automation.

In addition to engineering development, different trade-off studies will be carried out to choose the best/optimal alternatives from the engineering and construction point of view, which will allow us to accurately estimate the CAPEX required for the implementation of new CSN units. SAXUM experience in similar project scopes is crucial for accomplishing CSN objectives for these greenfield projects related to clinker and cement production plants.

Basic and Detailed Engineering for Allura's Sand Grinding Project in Roaring River, North Carolina

The Allura/Elementia Roaring River Project located in North Carolina, USA, consists of a wet sand grinding plant to obtain sand with a certain specific and uniform size particle/granulometry. The process consists of a sand reception hopper which will be fed by a front-end loader or other means and a hopper below, which will feed a belt that will transport the material to the mill. The milling will be wet, using a ball mill and will be in a closed circuit with recirculation.

The material at the exit of the mill will be a pulp (solid + liquid) which will be fed through a pulp pump to a classifying hydro-cyclone, in which the material with the appropriate size/fineness will go to the next phase of the process and the coarse material will be returned to the mill. After the hydro-cyclone, the pulp will be sent to a thickener tank, where the maximum amount of water will be removed from the pulp to obtain the final product sought. A European OEM has been selected for the ball mill and local/USA equipment suppliers for the rest of the equipment.

For this project, Allura has selected SAXUM Engineering LLC based in Irving, Texas/USA, to perform the Basic and Detailed Engineering, including Civil/Structural, Mechanical/Piping, and Electrical/Instrumentation & Controls, as well as layout analysis.

SAXUM will integrate the complete project in a single 3D model, bringing together all Civil, Structural, Mechanical, Piping, E&I, and equipment. This will allow for a full and comprehensive project review and early detection of possible interferences between structures, equipment, rack supports, etc.

For this project, SAXUM has assigned an experienced team of engineers and designers. SAXUM’s responsibility in this Allura project includes the PE stamping and sign-off by registered professionals in the state of North Carolina.

SAXUM will also assist Allura during the construction phase of this project.
