    Robit’s Rbit and Haul Sub drilling systems: maintenance and cost notes for mine engineers

    Robit’s Rbit and Haul Sub drilling systems: maintenance and cost notes for mine engineers

    First reported on Australian Mining

    30 Second Briefing

    Robit is rolling out its Rbit drill bit series and Haul Sub adaptor system to cut unplanned maintenance and extend tool life in hard-rock production drilling. The Rbit design focuses on optimised button layout, improved flushing and wear-resistant carbide grades, while the Haul Sub allows damaged threads to be cut back and re-used instead of scrapping entire drill strings. Contractor Bohus Bergsprängning is among early adopters, signalling potential reductions in bit consumption, rig downtime and per‑metre drilling costs for Scandinavian quarries and underground mines.

    Technical Brief

    • Haul Sub adaptor is welded between the drill tube and shank adapter, creating a sacrificial threaded section.
    • Once the sacrificial thread is worn, it is cut off and a new Haul Sub welded on.
    • Contractor reports fewer complete rod changes, reducing manual handling exposure around the feed beam.
    • Reduced scrapping of full drill tubes directly cuts steel consumption and transport requirements for replacement rods.
    • Similar adaptor concepts could be retrofitted to other top‑hammer fleets where thread wear governs rod retirement.

    Our Take

    Robit’s work with Bohus Bergsprängning in Australia sits alongside its managed service contract for drilling consumables at the Endeavor silver-zinc-lead mine in New South Wales, signalling a push to lock in long-term tooling and maintenance roles rather than just spot sales.

    Field trials at La Arena (gold-copper, Peru) and Kevitsa (nickel-copper, Finland) in our database show Robit deliberately proving its drilling tools in highly abrasive and geotechnically demanding conditions, which likely underpins the maintenance and productivity claims being promoted to Australian contractors.

    Orica’s Danafloat copper flotation move: integration and design notes for plant engineers

    Orica has moved into copper processing chemistry by acquiring FMC Corporation’s Danafloat™ range of high-performance flotation collectors, used for copper and other “future facing” commodities. The deal covers proprietary formulations designed to maximise sulphide ore recovery and improve concentrate grade while reducing reagent dosage and environmental impact. For concentrator operators, this adds a major explosives and blasting supplier into the flotation reagent supply chain, potentially enabling tighter integration between upstream fragmentation and downstream recovery optimisation.

    National Group backing mining excellence: project delivery lessons for engineers

    Queensland-based mining services provider National Group is sponsoring a community-focused award recognising resources companies that show strong engagement and deliver measurable change across the sector. The award targets operators and contractors working in Queensland’s coal, metals and quarrying projects, with assessment centred on local employment, training programmes and long-term community investment rather than short-term donations. For geotechnical and mining teams, this signals growing scrutiny of how project delivery, contractor selection and site rehabilitation strategies translate into tangible regional benefits.

    Smarter filtration solutions: dewatering and tailings design notes for plant engineers

    Smarter filtration solutions in wet mineral processing are focusing on high-pressure tower filter presses for slurry dewatering, such as Thejo’s vertical plate designs that deliver low-moisture filter cakes and high filtrate recovery. Suppliers are pairing these presses with automated cloth washing, cake discharge monitoring and optimised cycle control to stabilise throughput and reduce unplanned downtime. For plant designers, the shift is towards integrating filtration with upstream thickening and downstream dry stacking to cut fresh water intake and tailings storage volumes.
