INTRODUCTION
Mr. J. A. Bates of Magnesium Refractories Ltd. and Mr. R. A. Elliott, Consultant,
requested that a high quality magnesite concentrate be produced from approximately 1.0 tonne
of ore from Timmins, Ontario. In addition to the magnesite concentrate, quartz and talc
concentrates were requested to be produced.
Low silica content in the magnesite concentrate was very important. The
recovery of magnesite was of secondary importance. Details of the testwork are contained in this
report.
The testwork was observed and directed by Mr. R. A. Elliott.

2.3.3 Magnesite Concentrate Quality
A quality of magnesite concentrate with less than 1 0X0 SiO2 was not achieved by
bench or pilot plant test using these test conditions.
Suggestions to reduce the silica content:
1) Grind the feed ore to 10007o minus 100 mesh to grind down coarse quartz
particles which did not float
2) Extend the talc flotation time to remove the talc which hindered the
quartz flotation
3) Use pine oil as the frother to enhance talc and quartz removal
4) Evaluate collector

EQUIPMENT DESCRIPTION
Small Sala Mill
The Sala ball mill is an overflow-discharge mill with inside dimensions of 635mm
diameter and 1090mm length and a total volume of 0.34m3 . The Linatex rubber lining is smooth
with six equally spaced litter bars 25mm high by 50mm wide. The mill is on rubberized rollers,
which are driven by torque-arm speed reducers and V-belts from two 3.7KW electric motors. The
mill speed is 36.8 r.p.m. or 690Xo of critical speed.
g)___Power Calculations
The total power is measured by a Sangamo Type KYWP meter, equipped with a
rate meter and a cumulative meter. Power readings are based on instantaneous timed rate
readings of the disc in the meter. The time interval during which the rotating disc made a
specified number of revolutions is measured with a stopwatch. A nominal efficiency of 950Xo is
assumed for the power transmission. Thus the gross power is 950Xo of the total power. The no-
load power is calculated in the same manner, but with the mill operating empty. Net power is
equal to the gross power minus the no-load power.
760mm Sweco Screen
The 760mm diameter Sweco Vibro-Energy Separator was used to classify the
Sala mill discharge. The screen used was:
Aperture in micrometres
80 mesh 178
Denver 20L Conditioner
The tank dimensions are 305mm diameter by 380mm depth with a side outlet for
20L capacity. The agitation is imparted by two opposed-pitch three and two bladed axial-flow
impellers of 100mm and 76mm diameter rotating at a shaft speed of approximately 1150 r.p.m.
Equipment Description
l 2
The drive is from a 0.75KW motor through V-belts and pulley. This conditioner was used ahead of
the Talc flotation circuit to modify the pH feeding the flotation circuit.
Denver Sub-A No.7 Flotation Cells
Two poly-urethane lined Denver Sub-A No.7 cells were used in the Talc flotation
circuit. Each cell has a volume of 28L and the mechanism is driven through V-belt and pulleys by
a 0.37KW motor. Air is self induced.
Denver Sub-A No. 5 Flotation Cells
Each cell has a volume of 7.7L and the mechanism is driven through V-belts and
pulleys by a 0.37KW motor. Air is self induced. The cells are poly-urethane lined and grouped in
a bank of four cells in series. These cells were used for the quartz flotation.

Calcine Production Test C1:
19 kg of sample from PP2 were calcined by the following procedure:
1. Approximately 2 kg of magnesite was placed in a tray.2. The tray was transferred to a high temperature muffle preheated to 7500C.3. The sample was calcined at temperature for a minimum of 6 hours.4. The tray was removed from the furnace and the contents air cooled.
HCI Leach Test No. 1:
Leaching of Quartz Concentrate from PP2
1. 1 kg of PP-2 quartz concentrate was pulped with 2L of water. The pulp was constantly mechanically agitated during leaching process.
2. 2L of HCI was slowly added (approximately 15 mL/minute). A strong froth was created when the acid contacted the pulp.
3. The mixture was heated to a gentle boil and allowed to continue boiling until reaction was complete. Upon completion the residue was allowed to settle to the bottom of the 4L beaker.
4. The residue was filtered and washed three times. The residue was then dried and assayed.
Results The acid leach residue assayed Q .0% Fe and 63.lVo SiO2-
Calcine Production Test C2
The Jones middling and non-mags of Test No. 3 (21.1 kg were used to produce calcine by the same procedure as in C1).

Hydration of MaQ
1. Approximately 10 kg of calcined MgO were combined and riffled in 1 kg charges.
2. Separate charges were hydrated by placing the MgO powder in a pyrex dish with
approximately 440 mL of water. This mixture was placed in a drying oven set at
2500F for approximately 12 hours. The average weight gain of the dried powder
was 200Xo.
3. The hydrated 1 kg charges were ground in pebble mills at a rate of 2.5 hours per kg
of powder. This gives a surface area of approximately 6400 cm27g.

Dear Sir:
RECEIVED05 1990
MINING LANDS SECTION
The following reports are submitted along, with copies of invoices and payments for assessment credits on the attached claims.
Bulk samples of ore were taken from a previously blasted area on the claims and were sent to Lakefield Research, Lakefield, Ontario. Flotation tests were done at Lakefield Research for preparation of magnesite concentrate which was calcined and then taken elsewhere for compaction and dead burning to produce refractory grain magnesia for market evaluation. A copy of the Lakefield report covering the flotation test work is attached.
Some of the concentrate, both in the magnesite form and in the form of calcined magnesia were submitted to a large magnesium metal operation in Eastern Canada. They raised questions about the content of some of the minor constituents and further work was done at Lakefield Research to try and determine the source of these contaminants. Copies of this work are also attached. This work is continuing.
Yours truly,
R.A. Elliott

MINING LANDS SECTIONDear Mr. Elliot:
Re: LR3778
Please find enclosed two samples produced from magnesite concentrate, provided
by Mr. B. Wyslouzil.
Sample C4 is calcine without grinding or hydration as requested, approximately 2 Ibs. to fill your client's needs.
Sample C5 is calcine which was ground and hydrated. C5 weighs approximately 2.5 Ibs.
The procedures used to generate each sample are attached.
Yours truly, LAKEFIELD RESEARCH

CALCINE PRODUCTION
Tests C4 and C5:
Magnesite samples, from B. Wyslouzil, were calcined by the following procedure:
1. Less than 1.5 kg of magnesite was placed in a tray.
2. The tray was transferred to a high temperature muffle, preheated to l SOOT.
3. The sample was calcined at temperature for a minimum of 6 hours.
4. The furnace was shut off, the door opened, the tray air cooled and removed.
C5 GRINDING AND HYDRATION
Test C5:
Approximately one kg of calcine was dry ground, for 5 hours in the Pebble mill
with 19.1 kg of ceramic balls.
The ground charge was placed in a pyrex dish and 440 mL of 1200F water was added. The mixture was placed in a drying oven, set at 2500F for approximately 12 hours.
A 50 g sample was removed for surface area determination.

TEST NO. JG1
PURPOSE.: To examine B and Nl dissolution characteristics from tourmaline
concentrate.
PROCEDURE: Prepare tourmaline concentrate irom hand picked specimen in
magnesite. Crush and concentrate as much as possible using Frantz
Isodynamic separator. Hand mortar to -200 mesh and split concentrate
into 3 tractions. Store 1 fraction, submit 1 fraction for head analysis and
leach 1 fraction sequentially in 200 ml glass volumetric with 1N, 3N and
6N HCI. Repeat test with 1N, 3N and 6N HCI and no sample to determine
B dissolution trom glass.

OBSERVATIONS:
1. The leach residue represented 28.5V0 ol the feed weight and assayed Q.19% Ni,
•cO.0005% B and ao.1% Mg (calculated). Unfortunately the Mg assay of the residue was
not measured. It had been assumed that the Mg would dissolve and the emphasis was
placed on the NI and B analyses of the residue.
2. The calculated head tor NI was the same as the direct head * 0.1 3Vo Ni. The NI data Is
excellent.
3. The calculated head for B was 2x the direct head but the results suggest that virtually all
the B leached out. The residue assayed •tO.OOOB'yo B.
4. The relatively low Mg dissolution was unexpected. The results suggest that Mg silicate
was present but this is doubtful.
RECOMMENDATION'
1 . Repeat the test on the 1 .045 g sample in storage but using only the 6N HCI leach. Assay
the residue for NI, B and Mg. Conduct the test in a teflon volumetric but run a standard
leach without sample to determine possible background interference.
2. Repeat the 6N HCI leach on a 20 g cut section of tourmaline In magnesite for 1 week.
Observe the reaction. Replace the solution every 24 hours and assay for B, Ni and Mg.
